Chris Lattner ef5cd1d3cf Teach legalize to promote copy(from|to)reg, instead of making the isel pass
do it.  This results in better code on X86 for floats (because if strict
precision is not required, we can elide some more expensive double -> float
conversions like the old isel did), and allows other targets to emit
CopyFromRegs that are not legal for arguments.
