AMDGPU: Address todo for handling 1/(2 pi)

You need to check bitwidth here. 0x3118 is a valid float 1.7612E-41. I assume same is true for double.

.bitwiseIsEqual already checks the FP semantic type. This isn't a floating point compare

3457

The BitsToFloat shouldn't be used for half though

[arsenm]

Don't use BitsTo*, add f16/f64 tests

LGTM
