Put a heuristic in place to prevent GVN from falling into bad cases with massively complicated CFGs.
This speeds up a particular testcase from 12+ hours to 5 seconds with little perceptible loss of quality.

Also, fix method lookup to not use LLVM module symbol table.

of two, and to not need a scratch std::vector. Also, use the
SelectionDAG's topological sort in LegalizeDAG instead of having
a separate implementation.

put each major step in a separate function. This makes the high
level sequence of events easier to follow.

where an appropriate reg-to-reg copy is not available.

str() mirrors the same method in std::ostringstream.
str() flushes the buffered stream contents to string and returns a reference to the string.

 - Only supports simple assignment and atomic semantics are ignored.
 - Not quite usable yet because the methods do not actually get added
   to the class metadata.
 - Added ObjCPropertyDecl::getSetterKind (one of Assign, Copy, Retain).
 - Rearrange CodeGenFunction so synthesis can reuse function prolog /
   epilog code.

Respect isReadOnly when generating synthesized method decls.

assign it to a version of the xmm register with the regclass that matches its
type.  This fixes PR2715, a bug handling some crazy xpcom case in mozilla.

Move implicit Obj-C param creation into ObjCMethodDecl.
 - Add ObjCMethodDecl::createImplicitParams.
 - Remove ObjCMethodDecl::set{Self,Cmd}Decl
 - Remove Sema::CreateImplicitParameter

No (intended) functionality change.

 - Change enum name to Kind.
 - Change enum constants to English strings.

Also, fix getPropertyImplementation (which probably should be renamed)

 - Also, fix Parser to construct proper SetterName selector (should be
   lifted out of parser though).

RecyclingAllocator, but this change is needed for the nodes
to actually be recycled. This cuts SelectionDAG's memory
usage high-water-mark in half in some cases.

Throw the switch to allow FastISel to emit instructions whose return types different from their inputs.  Next step: adding lowering pattens in FastISel that actually use these newly available opcodes.
