Jakob Stoklund Olesen bceb9e5c05 Add an option to disable spill hoisting.
When -split-spill-mode is enabled, spill hoisting is performed by
SplitKit instead of by InlineSpiller.  This hidden command line option
is for testing the splitter spill mode.

Bruno Cardoso Lopes fa1ca3070b Change all checks regarding the presence of any SSE level to always
take into consideration the presence of AVX. This change, together with
the SSEDomainFix enabled for AVX, makes AVX codegen to always (hopefully)
emit the same code as SSE for 128-bit vector ops. I don't
have a testcase for this, but AVX now beats SSE in performance for
128-bit ops in the majority of programas in the llvm testsuite

Jakob Stoklund Olesen c94c967656 Count correctly when a COPY turns into a spill or reload.
The number of spills could go negative since a folded COPY is just a
spill, and it may be eliminated.

Jim Grosbach ebdf32f907 Assmebler symbol attribute directives don't work on temporary symbols.

Jim Grosbach a9aa3c18e3 Handle missing newline at EOF more gracefully in MC AsmLexer.
If we see an EOF w/o a preceding end-of-line, return an EndOfStatement
token before returning the Eof token.

Jakob Stoklund Olesen 07b3503f8b Trace through sibling PHIs in bulk.
When traceSiblingValue() encounters a PHI-def value created by live
range splitting, don't look at all the predecessor blocks.  That can be
very expensive in a complicated CFG.

Instead, consider that all the non-PHI defs jointly dominate all the
PHI-defs.  Tracing directly to all the non-PHI defs is much faster that
zipping around in the CFG when there are many PHIs with many
predecessors.

This significantly improves compile time for indirectbr interpreters.

Jakob Stoklund Olesen ae4471af1b Use getPrevSlot() instead of getPrevIndex().
The getPrevIndex() function moves to the same slot in the previous
instruction.  For getVNInfoBefore(), we just need the previous slot in
the same instruction.

Jakob Stoklund Olesen b8b1d4c435 Speed up LiveIntervals::shrinkToUse with some caching.
Blocks with multiple PHI successors only need to go on the worklist
once.  Use a SmallPtrSet to track the live-out blocks that have already
been handled.  This is a lot faster than the two live range check we
would otherwise do.

Also stop recomputing hasPHIKill flags.  Like RenumberValues(), it is
conservatively correct to leave them in, and they are not used for
anything important.

Jakob Stoklund Olesen fb75d78d33 Revert r139782, "RemoveCopyByCommutingDef doesn't need hasPHIKill()."
It does, after all.

RemoveCopyByCommutingDef rewrites the uses of one particular value
number in A. It doesn't know how to rewrite phi uses, so there can't be
any.

Nick Lewycky e8cdaddcf8 Despite what the GCC wiki says, a quick search shows that
DW_AT_GNU_template_name = 0x2110, not 0x2108. That would explain those 
attr #0x2110 under the DW_TAG_GNU_template_template_param I'm seeing. Migrate
from documented values to reality.
