Matt Arsenault a48e15c6cb Split sources for amdgcn and r600 
Most files remain in a common amdgpu directory.

Also switches barriers to to use convergent,
and use llvm.amdgcn.s.barrier.

This now requires 3.9/trunk to build amdgcn.

Tom Stellard 6c7b86c106 Implement nextafter() builtin 
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.
