Michael Hudson-Doyle 6deb3c0619 runtime, runtime/cgo: conform to PIC register use rules in ppc64 asm 
PIC code on ppc64le uses R2 as a TOC pointer and when calling a function
through a function pointer must ensure the function pointer is in R12.  These
rules are easy enough to follow unconditionally in our assembly, so do that.
