[X86][SSE] LowerVectorAllZero - add support for masked OR-reductions

If we're masking the result of an OR-reduction before comparing against zero, we can fold this into the PTEST() / MOVMSK(CMPEQ()) codegen by pre-masking the source value.

This works particularly well on PTEST which performs the AND as part of its operation, but the MOVMSK variant also benefits for non-V2I64 cases.

Fixes PR44781

[lldb/Test] Introduce "assertSuccess"

Summary:
A lot of our tests do 'self.assertTrue(error.Success()'. The problem
with that is that when this fails, it produces a completely useless
error message (False is not True) and the most important piece of
information -- the actual error message -- is completely hidden.

Sometimes we mitigate that by including the error message in the "msg"
argument, but this has two additional problems:
- as the msg argument is evaluated unconditionally, one needs to be
  careful to not trigger an exception when the operation was actually
  successful.
- it requires more typing, which means we often don't do it

assertSuccess solves these problems by taking the entire SBError object
as an argument. If the operation was unsuccessful, it can format a
reasonable error message itself. The function still accepts a "msg"
argument, which can include any additional context, but this context now
does not need to include the error message.

To demonstrate usage, I replace a number of existing assertTrue
assertions with the new function. As this process is not easily
automatable, I have just manually updated a representative sample. In
some cases, I did not update the code to use assertSuccess, but I went
for even higher-level assertion apis (runCmd, expect_expr), as these are
even shorter, and can produce even better failure messages.

[ARM][MVE] Tail-predication: clean-up of unused code

After the rewrite of this pass (D79175) I missed one thing: the inserted VCTP
intrinsic can be cloned to exit blocks if there are instructions present in it
that perform the same operation, but this wasn't triggering anymore. However,
it turns out that for handling reductions, see D75533, it's actually easier not
not to have the VCTP in exit blocks, so this removes that code.

This was possible because it turned out that some other code that depended on
this, rematerialization of the trip count enabling more dead code removal
later, wasn't doing much anymore due to more aggressive dead code removal that
was added to the low-overhead loops pass.

[PDB] Defer public serialization until PDB writing

This reduces peak memory on my test case from 1960.14MB to 1700.63MB
(-260MB, -13.2%) with no measurable impact on CPU time. I'm currently
working with a publics stream that is about 277MB. Before this change,
we would allocate 277MB of heap memory, serialize publics into them,
hold onto that heap memory, open the PDB, and commit into it.  After
this change, we defer the serialization until commit time.

In the last change I made to public writing, I re-sorted the list of
publics multiple times in place to avoid allocating new temporary data
structures. Deferring serialization until later requires that we don't
reorder the publics. Instead of sorting the publics, I partially
construct the hash table data structures, store a publics index in them,
and then sort the hash table data structures. Later, I replace the index
with the symbol record offset.

This change also addresses a FIXME and moves the list of global and
public records from GSIHashStreamBuilder to GSIStreamBuilder. Now that
publics aren't being serialized, it makes even less sense to store them
as a list of CVSymbol records. The hash table used to deduplicate
globals is moved as well, since that is specific to globals, and not
publics.

[X86] Move frontend CPU feature initialization to a look up table based implementation. NFCI

This replaces the switch statement implementation in the clang's

I've used constexpr and copy of the FeatureBitset from

After the lookup the bitset is translated into strings for use
by the rest of the frontend code.

I had to modify the implementation of the FeatureBitset to avoid
bugs in gcc 5.5 constexpr handling. It seems to not like the
same array entry to be used on the left side and right hand side
of an assignment or &= or |=. I've also used uint32_t instead of
uint64_t and sized based on the X86::CPU_FEATURE_MAX.

I've initialized the features for different CPUs outside of the
table so that we can express inheritance in an adhoc way. This
was one of the big limitations of the switch and we had resorted
to labels and gotos.
