cmd/compile: add floating point min/max intrinsics on s390x
Add the VECTOR FP (MINIMUM|MAXIMUM) instructions to the assembler and
use them in the compiler to implement min and max.
Note: I've allowed floating point registers to be used with the single
element instructions (those with the W instead of V prefix) to allow
easier integration into the compiler.
