Aryadev Chavali dcedb70a5c Switched from floats to halfword
Registers are now just words, with pushing from and moving to
registers with specified subtypes just pushing those types into the
word registers.  That means there are 8 word registers which can act
as 16 half word registers, which themselves can act as 64 byte
registers.
