Fix the third (and last known) case of code update problems due

to LLVM IR changes with addr label weirdness. In the testcase, we

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

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.

Completely rewrite tblgen's type inference mechanism,
...
changing the primary datastructure from being a
"std::vector<unsigned char>" to being a new TypeSet class
that actually has (gasp) invariants!
This changes more things than I remember, but one major
innovation here is that it enforces that named input
values agree in type with their output values.
This also eliminates code that transparently assumes (in
some cases) that SDNodeXForm input/output types are the
same, because this is wrong in many case.
This also eliminates a bug which caused a lot of ambiguous
patterns to go undetected, where a register class would
sometimes pick the first possible type, causing an
ambiguous pattern to get arbitrary results.
With all the recent target changes, this causes no
functionality change!
