  1. [AArch64] Fix condition for "high-vector" DUP optimizations.

    AArch64 NEON has a bunch of instructions with a "2" suffix that extract
    the top half of the source vectors, instead of the bottom half.  We have
    some DAGCombines to try to take advantage of that.  However, they
    assumed that any EXTRACT_VECTOR was extracting the high half of the
    vector in question.

    This issue has apparently existed since the AArch64 backend was merged.

  7. [mips][micromips] Fix how values in .gcc_except_table are calculated

    When a landing pad is calculated in a program that is compiled for micromips
    with -fPIC flag, it will point to an even address.
    Such an error will cause a segmentation fault, as the instructions in
    micromips are aligned on odd addresses. This patch sets the last bit of the
    offset where a landing pad is, to 1, which will effectively be an odd
    address and point to the instruction exactly.

    r344591 fixed this issue for -static compilation.

    If the bitcast is between vector types with a different number of elements,
    the current code will produce bad IR along the lines of: icmp <N x i32> ..., <M x i32> <...>.

    This patch suppresses the transform if the bitcast changes the number of vector elements.

  26. GlobalISel: Implement narrowScalar for shift main type

    This is pretty much directly ported from SelectionDAG. Doesn't include
    the shift by non-constant but known bits version, since there isn't a
    globalisel version of computeKnownBits yet.

    This shows a disadvantage of targets not specifically which type
    should be used for the shift amount. If type 0 is legalized before
    type 1, the operations on the shift amount type use the wider type
    (which are also less likely to legalize). This can be avoided by
    targets specifying legalization actions on type 1 earlier than for
    type 0. (detail/ViewSVN)

  38. [DAGCombiner] fold add/sub with bool operand based on target's boolean contents
    I noticed that we are missing this canonicalization in IR:
    ...and then realized that we don't get this right in SDAG either,
    so this has to be fixed first regardless of what we choose to do in IR.

    The existing fold was limited to scalars and using the wrong predicate
    to guard the transform. We have a boolean contents TLI query that can
    be used to decide which direction to fold.

    This may eventually lead back to the problems/question in:
    ...but it makes no difference to that yet.

  46. [llvm-ar][libObject] Fix relative paths when nesting thin archives.

    When adding one thin archive to another, we currently chop off the relative path to the flattened members. For instance, when adding `foo/child.a` (which contains `x.txt`) to `parent.a`, when flattening it we should add it as `foo/x.txt` (which exists) instead of `x.txt` (which does not exist).

    As a note, this also undoes the `IsNew` parameter of handling relative paths in r288280. The unit test there still passes.

    This was reported as part of testing the kernel build with llvm-ar: (see the second point).

  55. [CodeView] Fix cycles in debug info when merging Types with global hashes

    When type streams with forward references were merged using GHashes, cycles
    were introduced in the debug info. This was caused by
    GlobalTypeTableBuilder::insertRecordAs() not inserting the record on the second
    pass, thus yielding an empty ArrayRef at that record slot. Later on, upon PDB
    emission, TpiStreamBuilder::commit() would skip that empty record, thus
    offseting all indices that came after in the stream.

    This solution comes in two steps:

    1. Fix the hash calculation, by doing a multiple-step resolution, iff there are
    forward references in the input stream.
    2. Fix merge by resolving with multiple passes, therefore moving records with
    forward references at the end of the stream.

    This patch also adds support for llvm-readoj --codeview-ghash.
    Finally, fix dumpCodeViewMergedTypes() which previously could reference deleted
