59f145598e Adding test cases showing the behavior of LoopUnrollPass according to optnone and optsize attributes
The unroll pass was disabled by clang in /Os. Those new test cases shows that the pass will behave correctly even if it is not fully disabled. This patch is related in some way to the clang commit (http://reviews.llvm.org/D19827), which re-enables the pass in /Os.

93aa5a1614 [InstCombine] Canonicalize icmp instructions based on dominating conditions.
Summary:
    This patch canonicalizes conditions based on the constant range information
    of the dominating branch condition.
    For example:

      %cmp = icmp slt i64 %a, 0
      br i1 %cmp, label %land.lhs.true, label %lor.rhs
      lor.rhs:
        %cmp2 = icmp sgt i64 %a, 0

    Would now be canonicalized into:

      %cmp = icmp slt i64 %a, 0
      br i1 %cmp, label %land.lhs.true, label %lor.rhs
      lor.rhs:
        %cmp2 = icmp ne i64 %a, 0

6c8ec11f5c [SimplifyCFG] isSafeToSpeculateStore now ignores debug info
This patch fixes PR27615.

@llvm.dbg.value instructions no longer count towards the maximum number of
instructions to look back at in the instruction list when searching for a
store instruction. This should make the output consistent between debug and
non-debug build.

7106e5387c Use ScopedPrinter in llvm-pdbdump
When printing raw PDB file fields, streams, and records, use the
ScopedPrinter class so we have consistency with llvm-readobj's output
format.

For the most part this is pretty mechanical, but I had to fix up the test
file to conform to the new YAMLesque output format. i added a few
additional helper functions to the ScopedPrinter such as one to print a
dotted version, etc.

48c396748c [RS4GC] Use SetVector/MapVector instead of DenseSet/DenseMap to guarantee stable ordering
Goal of this change is to guarantee stable ordering of the statepoint arguments and other 
newly inserted values such as gc.relocates. Previously we had explicit sorting in a couple
of places. However for unnamed values ordering was partial and overall we didn't have any 
strong invariant regarding it. This change switches all data structures to use SetVector's
and MapVector's which provide possibility for deterministic iteration over them.
Explicit sorting is now redundant and was removed.

7a66203c71 [Sparc] Implement __builtin_setjmp, __builtin_longjmp back-end.
This code implements builtin_setjmp and builtin_longjmp exception handling intrinsics for 32-bit Sparc back-ends.

The code started as a mash-up of the PowerPC and X86 versions, although there are sufficient differences to both that had to be made for Sparc handling.

Note: I have manual tests running. I'll work on a unit test and add that to the rest of this diff in the next day.

Also, this implementation is only for 32-bit Sparc. I haven't focussed on a 64-bit version, although I have left the code in a prepared state for implementing this, including detecting pointer size and comments indicating where I suspect there may be differences.

c1b3a43079 [ConstantFolding, ValueTracking] Fold constants involving bitcasts of ConstantVector
We assumed that ConstantVectors would be rather uninteresting from the
perspective of analysis.  However, this is not the case due to a quirk
of how LLVM handles vectors of i1.  Vectors of i1 are not
ConstantDataVectors like vectors of i8, i16, i32 or i64 because i1's
SizeInBits differs from it's StoreSizeInBytes.  This leads to it being
categorized as a ConstantVector instead of a ConstantDataVector.

Instead, treat ConstantVector more uniformly.

This fixes PR27591.

105d2da2bd Produce another specific error message for a malformed Mach-O file when a load
command has a size less than 8 bytes.

I think the existing test case in test/Object/macho-invalid.test for
macho64-invalid-too-small-load-command was trying to test for this but that
test case triggered a different error given how it was constructed.  So I
constructed a new test case that would trigger this specific error.

I also changed the error message to be consistent with the other malformed Mach-O
file error messages.  I also removed object_error::macho_small_load_command from
Object/Error.h as it is not needed and can just use object_error::parse_failed
and let the error message string distinguish the error.
