ec2e96e628 llvm-mc/AsmParser: Match hard coded registers (e.g. 'shldl %cl, %eax, %eax')
We now match all of 403.gcc (as emitted by clang). :)

c2a229453e change the -x86-asm-syntax=intel/att flag to be in X86TAI
instead of X86 Subtarget.  This elimianates dependencies on
X86Subtarget from X86TAI.

a74023896f Change the asmprinter to print the comment character before the
"inlineasmstart/end" strings so that the contents of the directive
are separate from the comment character.  This lets elf targets
get #APP/#NOAPP for free even if they don't use "#" as the comment
character.  This also allows hoisting the darwin stuff up to the
shared TAI class.

63f93255ae Add 'isCodeGenOnly' bit to Instruction .td records.
- Used to mark fake instructions which don't correspond to an actual machine
   instruction (or are duplicates of a real instruction). This is to be used for
   "special cases" in the .td files, which should be ignored by things like the
   assembler and disassembler. We still need a good solution to handle pervasive
   duplication, like with the Int_ instructions.

 - Set the bit on fake "mov 0" style instructions, which allows turning an
   assembler matcher warning into a hard error.

 - -2 FIXMEs.

45bdc96988 split "JumpTableDirective" (an existing hack) into a PIC and nonPIC
version.  This allows TAI implementations to specify the directive to use
based on the mode being codegen'd for.

The real fix for this is to remove JumpTableDirective, but I don't feel
like diving into the jumptable snarl just now.
