-Instructions classification:
-FP    : add, sub, mul, sdiv, copy, par, arg
-Maybe : and, or, xor, cmp(6)
-Non FP: udiv, srem, urem, store(4), load(7),
-        ext(7), alloc(5), parc, argc, call
-
-15 bits for operations  32768
--1 bit for s,d          16384
-
-New conversion instructions:
- - Bitcast conversion between fp and ints. bcast
- - Convert fp to/from int. ftosi sitof (only signed at first, truncation)
- - Convert single to/from double fconv
-
-Summary:
-	Add bcast, ftosi sitof, fconv
-	Add a 'floating point' bit to instructions
-	Conversions from/to unsigned types are hard!
-	I need to find a reference for that.
-
-Roadmap in isel.
-	Make sure all floating point immediates are accessed
-	through a memory load.  The load can be fused in some
-	instructions (add, sub, mul, div).  This should be
-	handled similarly to the large integer constants.
-	Note: contrary to large constants, the transformation
-	also needs to be run on phi nodes!
-
-	Complete ABI implementation, we should only need the
-	movsd instruction to transfer between sse registers and
-	memory.
