Introduce an abstraction layer for reporting diagnostics, so as to avoid
directly using the native GCC interfaces such as "error_at",
"warning_at", "open_quote", "close_quote", etc. The new interfaces have
the same look and feel as the GCC equivalents, but make calls into
back-end functions to allow the back end to select the proper final
reporting routine.
