i965: Drop bogus F32TO16/F16TO32 instructions on Broadwell - use MOV.
Broadwell removed the F32TO16 and F16TO32 instructions. However, it has
actual support for HF values, so they're actually just MOV.
Fixes vs-packHalf2x16 and vs-unpackHalf2x16 tests (both the ARB
extension and ES 3.0 variants).
v2: Emulate F32TO16's align16 zeroing bug, since Chad's front end code
relies on it happening. We can probably refactor this code to be
better later.
