There are two implementations of nextafter():
1. Using clang's __builtin_nextafter.  Clang replaces this builtin with
a call to nextafter which is part of libm.  Therefore, this
implementation will only work for targets with an implementation of
libm (e.g. most CPU targets).

2. The other implementation is written in OpenCL C.  This function is
known internally as __clc_nextafter and can be used by targets that
don't have access to libm.

This fixes getSystemRegistryString() in WindowsToolChain.cpp to
make sure that the VS version that it picks has an InstallDir.
Previously we would look for the highest version os VS and check
for InstallDir afterwards.

Fixed an issue where environment variables that contained special characters '$' and '#' would hose up the GDB server packet. We now use the QEnvironmentHexEncoded packet that has existed for a long time when we need to. Also added code that will stop sending the QEnvironmentHexEncoded and QEnvironment packets if they aren't supported.

Removed the -t options from linking flags to avoid having the linker print out all .o files it was linking with.

We previously failed to check whether the SUCCESS variable was set,
and would thus always exit with a failure if vs2012 didn't exist.

The function is used by the machine verifier and checks that VOP*
instructions have legal operands.

llvm-svn: 192367

We can't enable the verifier for tests with SI_IF and SI_ELSE, because
these instructions are always followed by a COPY which copies their
result to the next basic block.  This violates the machine verifier's
rule that non-terminators can not folow terminators.

During instruction selection, we rewrite the destination register
class for MIMG instructions based on their writemasks.  This creates
machine verifier errors since the new register class does not match
the register class in the MIMG instruction definition.

We can avoid this by defining different MIMG instructions for each
possible destination type and then switching to the correct instruction
when we change the register class.

llvm-svn: 192365

This prevents the machine verifier from complaining about uses of
an undefined physical register.

StructurizeCFG pass allows to make complex cfg reducible ; it allows a lot of
shader from shadertoy (which exhibits complex control flow constructs) to works
correctly with respect to CFG handling (and allow us to detect potential bug in
other part of the backend).

We provide a cmd line argument to disable the pass for debug purpose.
