  1. Revert "[System Model] [TTI] Update cache and prefetch TTI interfaces"

    This broke some PPC prefetching tests.

    This reverts commit 9fdfb045ae8bb643ab0d0455dcf9ecaea3b1eb3c. (detail/ViewSVN)

  2. Move three folds for FADD, FSUB and FMUL in the DAG combiner away from Unsafe to more aligned checks that reflect context

    Summary: Unsafe does not map well alone for each of these three cases as it is missing NoNan context when accessed directly with clang.  I have migrated the fold guards to reflect the expectations of handing nan and zero contexts directly (NoNan, NSZ) and some tests with it.  Unsafe does include NSZ, however there is already precedent for using the target option directly to reflect that context.

    This reverts commit d5214dfa7b5650745eaeb102857c9e90adb16137.

    It's causing failures, both in our local CI and the PS4 Windows bot. (detail/ViewSVN)

  4. [System Model] [TTI] Update cache and prefetch TTI interfaces

    Rework the TTI cache and software prefetching APIs to prepare for the
    introduction of a general system model.  Changes include:

    - Marking existing interfaces const and/or override as appropriate
    - Adding comments
    - Adding BasicTTIImpl interfaces that delegate to a subtarget
    - Adding a default "no information" subtarget implementation

    Only a handful of targets use these interfaces currently: AArch64,
    Hexagon, PPC and SystemZ.  AArch64 already has a custom subtarget
    implementation, so its custom TTI implementation is migrated to use
    the new facilities in BasicTTIImpl to invoke its custom subtarget
    implementation.  The custom TTI implementations continue to exist for
    the other targets with this change.  They are not moved over to
    subtarget-based implementations.

    The end goal is to have the default subtarget implementation defer to
    the system model defined by the target.  With this change, the default
    subtarget implementation essentially returns "no information" for
    these interfaces.  None of the existing users of TTI will hit that
    implementation because they define their own custom TTI
    implementations and won't use the BasicTTIImpl implementations.

    Once system models are in place for the targets that use these
    interfaces, their custom TTI implementations can be removed.

  5. Recommit "[CommandLine] Remove OptionCategory and SubCommand caches from the Option class."

    Previously reverted in 364141 due to buildbot breakage, and fixed here
    by making GeneralCategory global a ManagedStatic.

    This change processes `OptionCategory`s and `SubCommand`s as they
    are seen instead of caching them in the Option class and processing
    them later.  Doing so simplifies the work needed to be done by the Global
    parser and significantly reduces the size of the Option class to a mere 64

    Removing  the `OptionCategory` cache saved 24 bytes, and removing
    the `SubCommand` cache saved an additional 48 bytes, for a total of a
    72 byte reduction.

  6. [X86] EltsFromConsecutiveLoads - clean up element size calcs. NFCI.

  7. [LoopRotate + MemorySSA] Keep an <instruction-cloned instruction> map.

    The map kept in loop rotate is used for instruction remapping, in order
    to simplify the clones of instructions. Thus, if an instruction can be
    simplified, its simplified value is placed in the map, even when the
    clone is added to the IR. MemorySSA in contrast needs to know about that
    clone, so it can add an access for it.
    To resolve this: keep a different map for MemorySSA.

  8. [ORC] Add custom IR compiler configuration to LLJITBuilder to enable obj caches.

    LLJITBuilder now has a setCompileFunctionCreator method which can be used to
    construct a CompileFunction for the LLJIT instance being created. The motivating
    use-case for this is supporting ObjectCaches, which can now be set up at
    compile-function construction time. To demonstrate this an example project,
    LLJITWithObjectCache, is included. (detail/ViewSVN)

  29. [NFC][InstCombine] Redundant masking before left-shift (PR42563)

    alive proofs:

    Indeed, not all of these patterns are canonical.
    But since this fold will only produce a single instruction
    i'm really interested in handling even uncanonical patterns.

    Other than these 6 patterns, i can't think of any other
    reasonable variants right now, although i'm sure they exist.

    For now let's start with patterns where both shift amounts are variable,
    with trivial constant "offset" between them, since i believe this is
    both simplest to handle and i think this is most common.
    But again, there are likely other variants where we could use
    ValueTracking/ConstantRange to handle more cases. (detail/ViewSVN)
