Evan Cheng ecb2908bf9 Sink codegen optimization level into MCCodeGenInfo along side relocation model 
and code model. This eliminates the need to pass OptLevel flag all over the
place and makes it possible for any codegen pass to use this information.

Bruno Cardoso Lopes c85e3ff334 Mips MC object code emission improvements: 
"With this patch we can now generate runnable Mips code through LLVM
direct object emission. We have run numerous simple programs, both C
and C++ and with -O0 and -O3 from the output. The code is not production
ready, but quite useful for experimentation." Patch and message by
Jack Carter

James Molloy 4c493e8050 Refactor instprinter and mcdisassembler to take a SubtargetInfo. Add -mattr= handling to llvm-mc. Reviewed by Owen Anderson.

Evan Cheng 2bb4035707 Move TargetRegistry and TargetSelect from Target to Support where they belong. 
These are strictly utilities for registering targets and components.

Evan Cheng 4d6c9d711d Some refactoring so TargetRegistry.h no longer has to include any files 
from MC.

Evan Cheng 8c886a40d2 Combine all MC initialization routines into one. e.g. InitializeX86MCAsmInfo, 
InitializeX86MCInstrInfo, etc. are combined into InitializeX86TargetMC.

Evan Cheng efd9b4240f - Move CodeModel from a TargetMachine global option to MCCodeGenInfo. 
- Introduce JITDefault code model. This tells targets to set different default
  code model for JIT. This eliminates the ugly hack in TargetMachine where
  code model is changed after construction.

Evan Cheng 2129f59637 Introduce MCCodeGenInfo, which keeps information that can affect codegen 
(including compilation, assembly). Move relocation model Reloc::Model from
TargetMachine to MCCodeGenInfo so it's accessible even without TargetMachine.

better location welcome).

Evan Cheng d60fa58ba1 Sink getDwarfRegNum, getLLVMRegNum, getSEHRegNum from TargetRegisterInfo down 
to MCRegisterInfo. Also initialize the mapping at construction time.

This patch eliminate TargetRegisterInfo from TargetAsmInfo. It's another step
towards fixing the layering violation.
