Correct documented spelling of ffinite-math to ffinite-math-only

This is to correct
ffinite-math-only is a gcc option.  That is the correct spelling.

[clang][SourceManager] cache Macro Expansions

A seemingly innocuous Linux kernel change [0] seemingly blew up our
compile times by over 3x, as reported by @nathanchance in [1].

The code in question uses a doubly nested macro containing GNU C
statement expressions that are then passed to typeof(), which is then
used in a very important macro for atomic variable access throughout
most of the kernel. The inner most macro, is passed a GNU C statement
expression.  In this case, we have macro arguments that are GNU C
statement expressions, which can contain a significant number of tokens.
The upstream kernel patch caused significant build time regressions for
both Clang and GCC. Since then, some of the nesting has been removed via
@melver, which helps gain back most of the lost compilation time. [2]

Profiles collected [3] from compilations of the slowest TU for us in the
kernel show:
* 51.4% time spent in clang::TokenLexer::updateLocForMacroArgTokens
* 48.7% time spent in clang::SourceManager::getFileIDLocal
* 35.5% time spent in clang::SourceManager::isOffsetInFileID
(mostly calls from the former through to the latter).

So it seems we have a pathological case for which properly tracking the
SourceLocation of macro arguments is significantly harming build
performance. This stands out in referenced flame graph.

In fact, this case was identified previously as being problematic in
commit 3339c568c4 ("[Lex] Speed up updateConsecutiveMacroArgTokens (NFC)")

Looking at the above call chain, there's 3 things we can do to speed up
this case.

1. TokenLexer::updateConsecutiveMacroArgTokens() calls
   SourceManager::isWrittenInSameFile() which calls
   SourceManager::getFileID(), which is both very hot and very expensive
   to call. SourceManger has a one entry cache, member LastFileIDLookup.
   If that isn't the FileID for a give source location offset, we fall
   back to a linear probe, and then to a binary search for the FileID.
   These fallbacks update the one entry cache, but noticeably they do
   not for the case of macro expansions!

   For the slowest TU to compile in the Linux kernel, it seems that we
   miss about 78.67% of the 68 million queries we make to getFileIDLocal
   that we could have had cache hits for, had we saved the macro
   expansion source location's FileID in the one entry cache. [4]

   I tried adding a separate cache item for macro expansions, and to
   check that before the linear then binary search fallbacks, but did
   not find it faster than simply allowing macro expansions into the one
   item cache.  This alone nets us back a lot of the performance loss.

   That said, this is a modification of caching logic, which is playing
   with a double edged sword.  While it significantly improves the
   pathological case, its hard to say that there's not an equal but
   opposite pathological case that isn't regressed by this change.
   Though non-pathological cases of builds of the Linux kernel before
   [0] are only slightly improved (<1%) and builds of LLVM itself don't
   change due to this patch.

   Should future travelers find this change to significantly harm their
   build times, I encourage them to feel empowered to revert this

2. SourceManager::getFileIDLocal has a FIXME hinting that the call to
   SourceManager::isOffsetInFileID could be made much faster since
   isOffsetInFileID is generic in the sense that it tries to handle the
   more generic case of "local" (as opposed to "loaded") files, though
   the caller has already determined the file to be local. This patch
   implements a new method that specialized for use when the caller
   already knows the file is local, then use that in
   TokenLexer::updateLocForMacroArgTokens.  This should be less
   controversial than 1, and is likely an across the board win. It's
   much less significant for the pathological case, but still a
   measurable win once we have fallen to the final case of binary
   search.  D82497

3. A bunch of methods in SourceManager take a default argument.
   SourceManager::getLocalSLocEntry doesn't do anything with this
   argument, yet many callers of getLocalSLocEntry setup, pass, then
   check this argument. This is wasted work.  D82498

With this patch applied, the above profile [5] for the same pathological
input looks like:
* 25.1% time spent in clang::TokenLexer::updateLocForMacroArgTokens
* 17.2% time spent in clang::SourceManager::getFileIDLocal
and clang::SourceManager::isOffsetInFileID is no longer called, and thus
falls out of the profile.

There may be further improvements to the general problem of "what
interval contains one number out of millions" than the current use of a
one item cache, followed by linear probing, followed by binary
searching. We might even be able to do something smarter in

[InstCombine] Drop debug loc in TryToSinkInstruction

The advice in HowToUpdateDebugInfo.rst is to "... preserve the debug
location of an instruction if the instruction either remains in its
basic block, or if its basic block is folded into a predecessor that
branches unconditionally".

TryToSinkInstruction doesn't seem to satisfy the criteria as it's
sinking an instruction to some successor block. Preserving the debug loc
can make single-stepping appear to go backwards, or make a breakpoint
hit on that location happen "too late" (since single-stepping from that
breakpoint can cause the function to return unexpectedly).

So, drop the debug location.

GlobalISel: Don't fail translate on weak cmpxchg

The translation of cmpxchg added by
9481399c0fd2c198c81b92636c0dcff7d4c41df2 specifically skipped weak
cmpxchg due to not understanding the meaning. Weak cmpxchg was added
in 420a216817def01816186910a2e35885c9201951. As explained in the
commit message, the weak mode is implicit in how
ATOMIC_CMP_SWAP_WITH_SUCCESS is lowered. If it's expanded to a regular
ATOMIC_CMP_SWAP, it's replaced with a strong cmpxchg.

This handling seems weird to me, but this was already following the
DAG behavior. I would expect the strong IR instruction to not have the
boolean output. Failing that, I might expect the IRTranslator to emit
ATOMIC_CMP_SWAP and a constant for the boolean.

Revert "[InstCombine] Drop debug loc in TryToSinkInstruction"

This reverts commit 903cf140d0118cf0d3f0f6f8967c6a20d9c5be6b.

This might be causing verifier failures on the bots, such as: "inlinable
function call in a function with debug info must have a !dbg location"

AMDGPU/GlobalISel: Fix some legalization of < dword vector stores

This avoids many instances of failing to legalize a vector truncstore
of <4 x s8> to 2 bytes. We don't perfectly handle every truncstore
yet, largely because the given set of legalization actions can't
actually differentiate between changing the result type and changing
the memory type.

LLParser: Accept align(N) as new syntax for parameter attribute

Every other value parameter attribute uses parentheses, so accept this
as the preferred modern syntax. Updating everything to use the new
syntax is left for a future change.
