Alexis Hunt 4ac55e33be Reimplement r132572 on top of a FoldingSet, thus hopefully solving both
the self-host failures and Chandler's concerns.

Jakob Stoklund Olesen fc205a5694 Teach TableGen to evaluate DAG expressions as set operations.
A TableGen backend can define how certain classes can be expanded into
ordered sets of defs, typically by evaluating a specific field in the
record. The SetTheory class can then evaluate DAG expressions that refer
to these named sets.

A number of standard set and list operations are predefined, and the
backend can add more specialized operators if needed. The -print-sets
backend is used by SetTheory.td to provide examples.

This is intended to simplify how register classes are defined:

  def GR32_NOSP : RegisterClass<"X86", [i32], 32, (sub GR32, ESP)>;

Greg Clayton a658fd26c3 Created a std::string in the base StopInfo class for the description and
cleaned up all base classes that had their own copy. Added a SetDescription
accessor to the StopInfo class.

Andrew Trick 49371f3f33 New BranchProbabilityInfo analysis. Patch by Jakub Staszak!
BranchProbabilityInfo provides an interface for IR passes to query the
likelihood that control follows a CFG edge. This patch provides an
initial implementation of static branch predication that will populate
BranchProbabilityInfo for branches with no external profile
information using very simple heuristics. It currently isn't hooked up
to any external profile data, so static prediction does all the work.

Devang Patel 1b291b22d0 Rework r132576.
Emit debug info only if there is an insertion point. The debug info should not force an insertion point. Codegen may later on decide to not emit code for some reason, see extensive comment in CodeGenFunction::EmitStmt(), and debug info should not get in the way.

Dan Gohman fb02cec44e Fix BasicAA's recursion detection so that it doesn't pessimize
queries in the case of a DAG, where a query reaches a node
visited earlier, but it's not on a cycle. This avoids
MayAlias results in cases where BasicAA is expected to
return MustAlias or PartialAlias in order to protect TBAA.

Jakob Stoklund Olesen b8bf3c0f8b Switch AllocationOrder to using RegisterClassInfo instead of a BitVector
of reserved registers.

allocation orders because RegisterClassInfo puts CSR aliases last.
