Ian Lance Taylor a70a2a8ad6 cmd/cgo: don't update each call in place
Updating each call in place broke when there were multiple cgo calls
used as arguments to another cgo call where some required rewriting.
Instead, rewrite calls to strings via the existing mangling mechanism,
and only substitute the top level call in place.

Fixes #28540
