I committed the first part of this (to trunk, for gcc 6) a while back, which embeds the driver into libgccjit, saving one external process call. Sadly I haven't made progress on embedding the assembler and linker, and I don't see this happening before feature freeze for gcc 6 (November 9th), as I'm working on a big overhaul of gcc's diagnostics (adding underlining of source code ranges) and various other usability improvements.
