No functional change intended.

Add an optimization that looks for a specific pair-wise add pattern and generates a vpaddl instruction instead of scalarizing the add.
Includes a test case.

[format strings] correctly suggest correct type for '%@' specifiers.  Fixes <rdar://problem/9607158>.

converted to add x,x if x is a undef.  add undef, undef does not guarantee
that the resulting low order bit is zero.

stderr output while at it).

PR10136: fix PPCTargetLowering::LowerCall_SVR4 so that a necessary CopyToReg doesn't appear to be dead.

Roman, since you're writing tests for other PPC-SVR4 vararg-related stuff, would you mind writing a test for this?

Apparently llvm itself generates undefined assembler local labels, causing
self-hosting problems with this patch. Reverting until that's sorted out.

When an assembler local symbol is used but not defined in a module, a
Darwin assembler wants to issue a diagnostic to that effect.

lexer is not a paste operator, it is a normal token.  This fixes a conformance
issue shown here:
http://p99.gforge.inria.fr/c99-conformance/c99-conformance-clang-2.9.html

and it defines away the crash from before.

Dan noted that this would work on the case shown on the commit message. I think
the case that was failing was a bb ending with a redundant conditional jump:

...
jne foo

foo:
...

I was unable to find any such case in the tests or in a debug build of clang,
so I will revert this part of the patch and watch the bots.

Measure the worst case number of probes for a miss instead of the less
conservative number of probes required for an insertion.

Lower the limit to < 6 probes worst case.

This doubles the size of the ARM and X86 hash tables, other targets are
unaffected. LiveVariables runs 12% faster with this change.

in a noexcept exception specification because it isn't part of the
canonical type. This ensures that we keep the exact expression written
in the noexcept exception specification, rather than accidentally
"adopting" a previously-written and canonically "equivalent" function
prototype. Fixes PR10087.
