[release-branch.go1.19] cmd/compile: defer transitive inlining until after AST is edited
This CL changes the inliner to process transitive inlining iteratively
after the AST has actually been edited, rather than recursively and
immediately. This is important for handling indirect function calls
correctly, because ir.reassigned walks the function body looking for
reassignments; whereas previously the inlined reassignments might not
have been actually added to the AST yet.
Fixes #59158.
This change was previously reverted as CL 481796 because the branch
was frozen for release.
