CS4240 GangweedGanggang RETARGETABLE tiger compiler that does not use LLIR

The coolest part of this compiler is that since I based the design off LLVM basically all of the heavy algorithms (frontend, regalloc, isel, lowering, etc.) are architecture independent.

• Frontend AST to IR
• Lowering and instruction selection (Architecture independent!!)
• Briggs register allocator (Architecture independent!!)
• Abstract target ISA interface
• MIPS32 ISA implementation
