Lang Hames 9f7d14756d Fix testers by removing dubious testcase for r209154.
It turns out that not all the world is x86-64. Who knew?

I'll get to work on a more appropriate test case for this patch.

Lang Hames 1fcbc08500 [RuntimeDyld] Fix x86-64 MachO GOT relocation handling.
For GOT relocations the addend should modify the offset to the
GOT entry, not the value of the entry itself. Teach RuntimeDyldMachO
to do The Right Thing here.

Fixes <rdar://problem/16961886>.

Benjamin Kramer 6dd790c617 Flip on vectorization of bswap intrinsics.
The cost model conservatively assumes that it will always get scalarized and
that's about as good as we can get with the generic TTI; reasoning whether a
shuffle with an efficient lowering is available is hard. We can override that
conservative estimate for some targets in the future.

Benjamin Kramer f3ad23551d SDAG: Legalize vector BSWAP into a shuffle if the shuffle is legal but the bswap not.
- On ARM/ARM64 we get a vrev because the shuffle matching code is really smart. We still unroll anything that's not v4i32 though.
- On X86 we get a pshufb with SSSE3. Required more cleverness in isShuffleMaskLegal.
- On PPC we get a vperm for v8i16 and v4i32. v2i64 is unrolled.

Saleem Abdulrasool 8bfb192ecd ARM: make libcall setup more table driven
Rather than create a series of function calls to setup the library calls, create

Saleem Abdulrasool a521845381 ARM: improve WoA ABI conformance for frame register
Windows on ARM uses R11 for the frame pointer even though the environment is a
pure Thumb-2, thumb-only environment.  Replicate this behaviour to improve
Windows ABI compatibility.  This register is used for fast stack walking, and
thus is part of the Windows ABI.

Saleem Abdulrasool f11f4b4e20 ARM: consolidate frame pointer register knowledge
Use the ARMBaseRegisterInfo to query the frame register.  The base register info
is aware of the frame register that is used for the frame pointer.  Use that to
determine the frame register rather than duplicating the knowledge.  Although,
the code path is slightly different in that it may return SP, that can only
occur if the frame pointer has been omitted in the machine function, which is
supposed to contain the desired value in that case.

Saleem Abdulrasool f3a5a5c546 Target: remove old constructors for CallLoweringInfo
This is mostly a mechanical change changing all the call sites to the newer
chained-function construction pattern.  This removes the horrible 15-parameter
constructor for the CallLoweringInfo in favour of setting properties of the call
via chained functions.  No functional change beyond the removal of the old
constructors are intended.

Saleem Abdulrasool 3f75acfbc7 Target: add support to build CallLoweringInfo
Rather than introducing an auxiliary CallLoweringInfoBuilder, add the methods to
do chained function construction directly to CallLoweringInfo.  This reduces the
monstrous 15-parameter constructor into a series of simpler (for some definition
of simpler) functions that control particular aspects of the call.  The old
interfaces can be completely removed once callers are moved to the new chained
constructor pattern.

Saleem Abdulrasool 9f664c1083 Target: change member from reference to pointer
This is a preliminary step to help ease the construction of CallLoweringInfo.
Changing the construction to a chained function pattern requires that the
parameter be nullable.  However, rather than copying the vector, save a pointer
rather than the reference to permit a late binding of the arguments.

David Majnemer 41d7dfe46a MachO: Add comments describing section flags/attrs
When pruning superfluous MachO structure definitions, I chose to keep

field values.

Bring these back to the copy in Support.  While doing this, fill in some
of the underdocumented definitions as well.

This patch fixes 3 issues introduced by r209049 that only showed up in on
the sanitizer buildbots. One was a typo in a compare. The other is a check to
confirm that the single differing value in the two incoming GEPs is the same
type. The final issue was the the IRBuilder under some circumstances would
build PHIs in the middle of the block.

Louis Gerbarg 8d2a43e9be Add support for combining GEPs across PHI nodes
Currently LLVM will generally merge GEPs. This allows backends to use more
complex addressing modes. In some cases this is not happening because there
is PHI inbetween the two GEPs:

  GEP1--\
        |-->PHI1-->GEP3
  GEP2--/

This patch checks to see if GEP1 and GEP2 are similiar enough that they can be
cloned (GEP12) in GEP3's BB, allowing GEP->GEP merging (GEP123):

  GEP1--\                     --\                           --\
        |-->PHI1-->GEP3  ==>    |-->PHI2->GEP12->GEP3 == >    |-->PHI2->GEP123
  GEP2--/                     --/                           --/

This also breaks certain use chains that are preventing GEP->GEP merges that the
the existing instcombine would merge otherwise.

Tests included.

This is not enough for all cases. An additional SELECTCombine optimization

be generated.
