Changes
  1. [X86] Add BLSR and BLSMSK to isUseDefConvertible.

    Unfortunately subo formation in CGP prevents obvious ways of
    testing this.

    But we already have BLSI in here and the flag behavior is
    well understood.

    Might become more useful if we improve PR42571. (detail/ViewSVN)

  2. [NFC]Fix IR/MC depency issue for function descriptor SDAG implementation

    Summary: llvm/IR/GlobalValue.h can't be included in MC, that creates a circular dependency between MC and IR libraries. This circular dependency is causing an issue for build system that enforce layering.

  3. [clang-scan-deps] Dependency directives source minimizer:
    single quotes are not digit separators after a valid character literal prefix

    The single quote character can act as a c++ digit separator.
    However, the minimizer shouldn't treat it as such when it's actually following
    a valid character literal prefix, like L, U, u, or u8.

  11. [AArch64][GlobalISel] Optimize compare and branch cases with G_INTTOPTR and unknown values.

    Since we have distinct types for pointers and scalars, G_INTTOPTRs can sometimes
    obstruct attempts to find constant source values. These usually come about when
    try to do some kind of null pointer check. Teaching getConstantVRegValWithLookThrough
    about this operation allows the CBZ/CBNZ optimization to catch more cases.

    This change also improves the case where we can't find a constant source at all.
    Previously we would emit a cmp, cset and tbnz for that. Now we try to just emit
    a cmp and conditional branch, saving an instruction.

    The cumulative code size improvement of this change plus D64354 is 5.5% geomean
    on arm64 CTMark -O0.

  13. [clang-doc] Add a structured HTML generator

    Implements an HTML generator.
    Nodes are used to represent each part of the HTML file. There are TagNodes that
    represent every HTML tag (p, h1, div, ...) and they have children nodes, which
    can be TagNodes or TextNodes (these nodes only have text).
    Proper indentation is rendered within the files generated by tool.
    No styling (CSS) is included.

  15. [GlobalISel][AArch64] Use getOpcodeDef instead of findMIFromReg

    Some minor cleanup.

    This function in Utils does the same thing as `findMIFromReg`. It also looks
    through copies, which `findMIFromReg` didn't.

    Delete `findMIFromReg` and use `getOpcodeDef` instead. This only happens in
    `tryOptVectorDup` right now.

    Update opt-shuffle-splat to show that we can look through the copies now, too.

  16. [GlobalISel][AArch64][NFC] Use getDefIgnoringCopies from Utils where we can

    There are a few places where we walk over copies throughout
    AArch64InstructionSelector.cpp. In Utils, there's a function that does exactly
    this which we can use instead.

    Note that the utility function works with the case where we run into a COPY
    from a physical register. We've run into bugs with this a couple times, so using
    it should defend us from similar future bugs.

    Also update opt-fold-compare.mir to show that we still handle physical registers
    properly.

  20. 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.

  22. [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
      implementation
    - 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.

  23. 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.

    Summary:
    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
    bytes.

    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.

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

    Summary:
    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.
