d30a98e43a Initial ARM/Thumb disassembler check-in. It consists of a tablgen backend
(RISCDisassemblerEmitter) which emits the decoder functions for ARM and Thumb,
and the disassembler core which invokes the decoder function and builds up the
MCInst based on the decoded Opcode.

Added sub-formats to the NeonI/NeonXI instructions to further refine the NEONFrm
instructions to help disassembly.

We also changed the output of the addressing modes to omit the '+' from the
assembler syntax #+/-<imm> or +/-<Rm>.  See, for example, A8.6.57/58/60.

And modified test cases to not expect '+' in +reg or #+num.  For example,

; CHECK:       ldr.w	r9, [r7, #28]

This does not move entirely to UAL syntax, since the default "increment after"

adjusted unittest

I have added some doxygen to OptionalOperandTraits,
so hopefully there will be no confusion in the future.

Incidentally OptionalOperandTraits is not used any more (IIUC),
but the obvious client would be BranchInstr, and I plan
to rearrange it that way.

without it as the safe compiler.

999aee24c7 Fix the third (and last known) case of code update problems due
to LLVM IR changes with addr label weirdness.  In the testcase, we
generate references to the two bb's when codegen'ing the first
function:

_test1:                                 ## @test1
	leaq	Ltmp0(%rip), %rax
..
	leaq	Ltmp1(%rip), %rax

Then continue to codegen the second function where the blocks
get merged.  We're now smart enough to emit both labels, producing
this code:

_test_fun:                              ## @test_fun
## BB#0:                                ## %entry
Ltmp1:                                  ## Block address taken
Ltmp0:
## BB#1:                                ## %ret
	movl	$-1, %eax
	ret

Rejoice.

4e815f8a8c MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue.
 - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol.

757e75b033 Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointing
to is local to the translation unit, we need to place fill the value of that
symbol into the non-lazy pointer.

This should conclude all Darwin changes for placing the LSDA into the TEXT
section. There is some cleanup to do. I.e., there's no longer a special need for
target-specific code here. But that can come later.
