Tanya Lattner e9e6705cf9 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.

Chad Rosier 818e116723 When pattern matching during instruction selection make sure shl x,1 is not 
converted to add x,x if x is a undef.  add undef, undef does not guarantee
that the resulting low order bit is zero.

Eli Friedman 164b1d753a 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?

Jim Grosbach ed1da49673 Revert 133010. Self-hosted buildbot unhappy. 
Apparently llvm itself generates undefined assembler local labels, causing
self-hosting problems with this patch. Reverting until that's sorted out.

Chris Lattner 848fa212e8 revert r133003 and fix the bug properly: the issue was that ## in a token 
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.

Rafael Espindola 5e85158321 Partial revert of 132882. 
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.

Jakob Stoklund Olesen 01eada6e5c Fix a compile time regression caused by too small hash tables. 
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.

Douglas Gregor d1cff77200 When profiling FunctionProtoTypes, don't canonicalize the expression 
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.

Nadav Rotem 10193c830b Add a testcase for checking the integer-promotion of many different vector 
types (with power of two types such as 8,16,32 .. 512).

Fix a bug in the integer promotion of bitcast nodes. Enable integer expanding
only if the target of the conversion is an integer (when the type action is
scalarize).

Add handling to the legalization of vector load/store in cases where the saved
vector is integer-promoted.

Chris Lattner f35de48c90 when compiling in a GNU mode (e.g. gnu99) treat VLAs with a size that can be folded to a constant 
as constant size arrays.  This has slightly different semantics in some insane cases, but allows
us to accept some constructs that GCC does.  Continue to be pedantic in -std=c99 and other
modes.  This addressed rdar://8733881 - error "variable-sized object may not be initialized"; g++ accepts same code

Bruno Cardoso Lopes 29386fb10d Since ARM's prefetch implementation predicted the presence of a instruction
