Tom Stellard 081e778d22 Implement async_work_group_copy builtin v3 
This is a simple implementation which just copies data synchronously.

v2:
  - Use size_t.

v3:
  - Fix possible race condition by splitting the copy among multiple
    work items.

Aaron Watry 947bdd059a math: Add tan implementation 
Uses the algorithm:
tan(x) = sin(x) / sqrt(1-sin^2(x))

An alternative is:
tan(x) = sin(x) / cos(x)

Which produces more verbose bitcode and longer assembly.

Either way, the generated bitcode seems pretty nasty and a more optimized
but still precise-enough solution is welcome.

Aaron Watry 951ab64d19 math: Add asin implementation 
asin(x) = atan2(x, sqrt( 1-x^2 ))

alternatively:
asin(x) = PI/2 - acos(x)

Use the atan2 implementation since it produces slightly shorter bitcode and
R600 machine code.

Otherwise the test evaluates to true on OpenCL 1.1 and earlier. Since we
therefore cannot use the CL_VERSION_?_? macros move them to the proper

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.
