This reapplies CL 481075, which was a reappliation of CL 478917.
This CL has been reverted twice now due to conflicts with CL 392854 /
CL 481061, which had bugs and had to be reverted.
Now this CL skips the conflicting changes to runtime/cgo/asm_ppc64x.s,
which will be merged directly into a new version of CL 392854 /
CL 481061. That way, if there are _more_ issues, this CL need not be
involved in any more reverts.

This is a cleanup to allow a consistent definitions of a function
descriptor on code shared between AIX and Linux. They need to be
declared in slightly different ways, but we can hide that in one
macro.
And, update all usage.

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.
