go/internal/gccgoimporter: update package to match std lib version

This CL makes sure it matches the original code in the std lib
but for the necessary changes to make the code work in x/tools
and with older versions of the std lib.

Notably, it brings over changes from https://golang.org/cl/119895
which were not ported to x/tools.

To simplify future comparisons with the original, streamlined
some comments.

Fixes golang/go#27891.
