compiler: better abstraction layer for diagnostics

Programming / Compilers / GCC - ian [138bc75d-0d04-0410-961f-82ee72b054a4] - 23 September 2016 14:36 UTC

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.
