[optimizing] Tune some x86_64 moves
Generate Moves of constant FP values by loading from the constant table.
Use 'movl' to load a 64 bit register for positive 32-bit values, saving
a byte in the generated code by taking advantage of the implicit
zero extension.
Change a couple of xorq(reg, reg) to xorl to (potentially) save a byte
of code per xor.
