Cherry Zhang ac59d7abb9 [release-branch.go1.16] cmd/compile, cmd/link: dynamically export writable static tmps
Static tmps are private to a package, but with plugins a package
can be shared among multiple DSOs. They need to have a consistent
view of the static tmps, especially for writable ones. So export
them. (Read-only static tmps have the same values anyway, so it
doesn't matter. Also Mach-O doesn't support dynamically exporting
read-only symbols anyway.)

Updates #44956.
Fixes #45030.
