Tom Stellard 17ec3a51c3 Implement fast_normalize builtin v4 
This implementation was ported from the AMD builtin library
and has been tested with piglit, OpenCV, and the ocl conformance tests.

v2:
  - Remove f suffix from constant in double implementations.
  - Consolidate implementations using the .cl/.inc approach.

v3:
 - Use __CLC_FPSIZE instead of __CLC_FP{32,64}

v4 (Jan Vesely):
 - Limit to single precision.

Aaron Watry f89bcca0b7 libclc/math: Add cospi 
Ported from the libclc/amd-builtins branch

v2: Rename sincos_f_piby4 to __libclc__sincosf_piby4
    Add cospi(double) implementation instead of using llvm.cos

Notes:
The sincosD_piby4.h file is mostly the same as the builtin implementation
released by AMD. The inline attribute declaration is changed, and M_PI is
used instead of a constant double. Otherwise, the only difference is that
the header explicitly enables the fp64 pragma.

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.

asin(x) = atan2(x, sqrt( 1-x^2 ))

alternatively:

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