051aaed43e 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.

e3f6755264 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.

9f105145af Add a null encoding for ireduce.i32.i64. 
This conversion doesn't require any code, we're just looking at the bits
differently.
