The vector types are straightforward and already implemented in clang - it's twisting llvm to represent two different triples in a single module and handling calls between them that I think will be extremely tedious to implement. Frama-c / libfirm / other-compiler-here means getting started quickly and then an uphill battle against the existing implementation. Grammar plus symbol table should yield ast, C doesn't need that much sema checking after the parse, build ssa form cranelift-style then write out asm. Should be a cheap enough exercise to walk through but the unknown unknowns will mess up the schedule and there's a day job in the way. One for a week's vacation I think.
