Patch by Mark Lam <mark.lam@apple.com> on 2012-07-13
Reviewed by Filip Pizlo.
Added some minor pretty printing in the OfflineASM.
Also added infrastruture for adding multiple types of comments and
annotations with the ability to enable/disable them in the generated
output as desired.
* GNUmakefile.list.am: add new file config.rb.
* llint/LLIntOfflineAsmConfig.h:
Added OFFLINE_ASM_BEGIN, OFFLINE_ASM_END, and OFFLINE_ASM_LOCAL_LABEL macros.
This will allow us to redefine these for other backends later.
* llint/LowLevelInterpreter32_64.asm:
Add a small example of instruction annotations for now.
* llint/LowLevelInterpreter64.asm:
Add a small example of instruction annotations for now.
* offlineasm/armv7.rb: Added handling of annotations.
* offlineasm/asm.rb:
Added machinery to dump the new comments and annotations.
Also added some indentations to make the output a little prettier.
* offlineasm/ast.rb: Added annotation field in class Instruction.
* offlineasm/backends.rb:
* offlineasm/config.rb: Added.
Currently only contains commenting options. This file is meant to be
a centralized place for build config values much like config.h for
JavaScriptCore.
* offlineasm/generate_offset_extractor.rb:
* offlineasm/instructions.rb:
* offlineasm/offsets.rb:
* offlineasm/opt.rb:
* offlineasm/parser.rb: Parse and record annotations.
* offlineasm/registers.rb:
* offlineasm/self_hash.rb:
* offlineasm/settings.rb:
* offlineasm/transform.rb:
* offlineasm/x86.rb: Added handling of annotations.

# Interesting invariant, which we take advantage of: branching instructions
# always begin with "b", and no non-branching instructions begin with "b".
# Terminal instructions are "jmp" and "ret".
