25fa4999ff [AArch64] Fix bugs in isel lowering replaceSplatVectorStore.
Summary:
Fix off-by-one indexing error in loop checking that inserted value was a
splat vector.

Add code to check that INSERT_VECTOR_ELT nodes constructing the splat
vector have the expected constant index values.

554fd99dd5 Revert "Use private linkage for MergedGlobals variables" on Darwin.
This is a partial revert of r244615 (http://reviews.llvm.org/D11942),
which caused a major regression in debug info quality.

Turning the artificial __MergedGlobal symbols into private symbols
(l__MergedGlobal) means that the linker will not include them in the
symbol table of the final executable. Without a symbol table entry
dsymutil is not be able to process the debug info for any of the
merged globals and thus drops the debug info for all of them.

This patch is enabling the old behavior for all MachO targets while
leaving all other targets unaffected.

2efc3cb968 [PowerPC] Add vector conversion builtins to altivec.h - LLVM portion
This patch corresponds to review:

10c7aaaee9 [AArch64] Enable merging of adjacent zero stores for all subtargets.
This optimization merges adjacent zero stores into a wider store.

e.g.,

strh wzr, [x0]
strh wzr, [x0, #2]
; becomes
str wzr, [x0]

e.g.,

str wzr, [x0]
str wzr, [x0, #4]
; becomes
str xzr, [x0]

Previously, this was only enabled for Kryo and Cortex-A57.

5dc7b67c62 [SystemZ] Use LLGT(R) instructions
This adds support for the 31-to-64-bit zero extension instructions
LLGT and LLGTR and uses them for code generation where appropriate.

Since this operation can also be performed via RISBG, we have to
update SystemZDAGToDAGISel::tryRISBGZero so that we prefer LLGT
over RISBG in case both are possible.  The patch includes some
simplification to the tryRISBGZero code; this is not intended
to cause any (further) functional change in codegen.

325cd2c98a ScheduleDAGInstrs: Add condjump deps to addSchedBarrierDeps()
addSchedBarrierDeps() is supposed to add use operands to the ExitSU
node. The current implementation adds uses for calls/barrier instruction
and the MBB live-outs in all other cases. The use
operands of conditional jump instructions were missed.

Also added code to macrofusion to set the latencies between nodes to
zero to avoid problems with the fusing nodes lingering around in the
pending list now.

d6fbe65040 AMDGPU: Emit runtime metadata as a note element in .note section
Currently runtime metadata is emitted as an ELF section with name .AMDGPU.runtime_metadata.

However there is a standard way to convey vendor specific information about how to run an ELF binary, which is called vendor-specific note element (http://www.netbsd.org/docs/kernel/elf-notes.html).

This patch lets AMDGPU backend emits runtime metadata as a note element in .note section.

f334ac19ad [AVX-512] Add lowering to cvttpd2udq/cvttps2udq for fptoui v2f64/2f32 to 2i32
This patch adds support for fptoui to 2i32 from both 2f64 and 2f32, building on Simon's change for the signed version in r284459 and using AVX-512 instructions.

If we don't have VLX support we need to use a 512-bit operation for v2f64->v2i32 and extract the result.

It also recognises that cvttpd2udq zeroes the upper 64-bits of the xmm result.
