commit 9dcfd362bcd6725fdf77151b8eed5ef41d3b189f
Author: Tom Stellard <thomas.stellard at amd.com>

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.
