ebf5c80959 Add Intel encodings for more conversion instructions. 
The following instructions have simple encodings:

- bitcast.f32.i32
- bitcast.i32.f32
- bitcast.f64.i64
- bitcast.i64.f64
- fpromote.f64.f32
- fdemote.f32.f64

Also add helper functions enc_flt() and enc_i32_i64 to
intel.encodings.py for generating the common set of encodings for an
instruction: I32, I64 w/REX, I64 w/o REX.

2b41f979cb Intel encodings for floating point bitwise ops. 
band, bor, bxor, band_not are all available on XMM registers.

4df6741a90 Add some signed int to float conversions. 
These map to single Intel instructions.

The i64 to float conversions are not tested yet. The encoding tables
can't yet differentiate instructions on a secondary type variable alone.
