Summary:
Most of the clang header patch by Simon Pilgrim @ SCEE.
Also fixed (or added) clang tests for these intrinsics.
LLVM tests to make sure we get the blend instruction out of these
shufflevectors are at http://reviews.llvm.org/D3600

We already had an assert for foo->RAUW(foo), but not for something like
foo->RAUW(GEP(foo)) and would go in an infinite loop trying to apply
the replacement.

Implement what we currently believe is the mangling scheme for RTTI
data. Tests will be added in a later commit which actually generate
RTTI data.

Normally, patterns like (add x, (setcc cc ...)) will be folded into
(csel x, x+1, not cc). However, if there is a ZEXT after SETCC, they
won't be folded. This patch recognizes the ZEXT and allows the
generation of CSINC.
This patch fixes bug 19680.
llvm-svn: 208660
source that provides a declaration from a hidden module would not have the
visibility of the produced definition checked. This might matter if an
external source chose to import a new module to provide an extra definition,
but is not observable with our current external sources.

The problem occurs when a non-i1 setcc is inverted. For example 'i8 = setcc' will get 'xor 0xff' to invert this. This is clearly wrong when the boolean contents are ZeroOrOne.
This patch introduces getLogicalNOT and updates SetCC legalisation to use it.

Right now the load may not get DCE'd because of the side-effect of updating
the base pointer.
This can happen if we lower a read-modify-write of an illegal larger type
(e.g. i48) such that the modification only affects one of the subparts (the
lower i32 part but not the higher i16 part). See the testcase.
In order to spot the dead load we need to revisit it when SimplifyDemandedBits
decided that the value of the load is masked off. This is the
CommitTargetLoweringOpt piece.
I checked compile time with ARM64 by sending SPEC bitcode files through llc.
No measurable change.

r208453 added support for having sret on the second parameter. In that
change, the code for copying sret into a virtual register was hoisted
into the loop that lowers formal parameters. This caused a "Wrong
topological sorting" assertion failure during scheduling when a
parameter is passed in memory. This change undoes that by creating a
second loop that deals with sret.
I'm worried that this fix is incomplete. I don't fully understand the
dependence issues. However, with this change we produce the same DAGs
we used to produce, so if they are broken, they are just as broken as
they have always been.

SECTDIFF relocations on 32-bit x86.
This fixes several of the MCJIT regression test failures that show up on 32-bit
builds.

For some impending improvements to debug info, LLVM will start assuming
that when the CU specifies llvm::DIBuilder::LineTablesOnly, the IR for
functions described by that CU will not include variables, types, etc.
(might be worth having some test coverage for GMLT + non-GMLT CUs,
especially with non-GMLT functions inlined into GMLT CU functions)

Tested by comparing make check VERBOSE=1 before and after to make sure
no tests are missed. (VERBOSE=1 prints the list of tests.)
Only one test :( remains where .cpp is required:
tools/llvm-cov/range_based_for.cpp:// RUN: llvm-cov range_based_for.cpp | FileCheck %s --check-prefix=STDOUT

The current patterns for REV16 misses mostn __builtin_bswap16() due to
legalization promoting the operands to from load/stores toi32s and then
truncing/extending them. This patch adds new patterns that catch the resultant
DAGs and codegens them to rev16 instructions. Tests included.

determine whether we get a mangling for a return type, rather than trying to
figure it out based on whether the mangled name ended with a '>'.

asan_cxx containts replacements for new/delete operators, and should
only be linked in C++ mode. We plan to start building this part
with exception support to make new more standard-compliant.

One test case had to be updated as it still had the extra indirection
for the variable list - removing the extra indirection got it back to
passing.

This is a slightly different approach to AArch64 (the base instruction
definitions aren't quite right for that to work), but achieves the
same thing and reduces C++ hackery in AsmParser.
