57a69e8177
- Moved main() into its own file gen/main.cpp - Fixed basic cross compilation - removed the option for setting OS - added support for llc's mattr, mcpu and mtriple switches - added basic ABI abstraction for return value rewrites, it's not perfect and will probably be completely rewritten once I get to handling parameter rewrites as well. - x86-64 extern(C) abi for cfloat returns now match (llvm-)gcc.
