x86 CPUs have a set of conversions of the form:
cvt{from}2{to}, wherefromandtocan be various XMM-held types (e.g.,ss,ps,si, etc.). These also have their truncating versions,cvtt*`. This change defines all of the instructions Cranelift needs (there are a few more) and wires them up in ISLE and in various emitted sequences. For these sequences, this chooses to factor out the choice of instruction into a closure since we no longer can pass around an opcode.<!--
