commit 4aebf69513ed6bd5f098c80cdad9b0801989e156
Author: Tom Stellard <thomas.stellard at amd.com>

Fix bitselect for float/double types v2
We need to reinterpret float/double types as uint/ulong in order to
perform the bitwise operations.
This has been tested with piglit, OpenCV, and the ocl conformance tests.
v2:
- Use vector operations rather than splitting vectors into scalar
components.
