Factor/Optimizing compiler

Factor's optimizing compiler generates machine code for x86 (32 and 64-bit), as well as PowerPC (32-bit only). The optimizing compiler is written entirely in Factor. Its implementation can be found in basis/compiler/ and basis/cpu/. The optimizing compiler uses SSA form internally, and performs various optimizations, such as Type inference, Escape analysis, Register allocation, and so on.
