Correlate stubs with functions in JIT: when emitting a stub, the JIT tells the memory manager which function
the stub will resolve.

currently doesn't pass in the Preprocessor from the driver, so we don't get
syntax highlighting when we create HTMLDiagnostics in that way.

Rename SDOperandImpl back to SDOperand.
Introduce the SDUse class that represents a use of the SDNode referred by
an SDOperand. Now it is more similar to Use/Value classes.

Patch is approved by Dan Gohman.

two worklists: for nodes whose locations are block edges with loop terminators
and another for nodes with all other locations.  We only dequeue from the loop
worklist when the other is empty.  Exploration of the graph is still in
reverse-BFS.

merge of r49785 (from branches/ggreif/use-diet): pass V to dyn_cast by const reference, this avoids copy-constructing and destructing all the time. especially important if these constructors are not accessible

Rewrite LiveVariable liveness computation. The new implementation is much simplified. It eliminated the nasty recursive routines and removed the partial def / use bookkeeping. There is also potential for performance improvement by replacing the conservative handling of partial physical register definitions. The code is currently disabled until live interval analysis is taught of the name scheme.

This patch also fixed a couple of nasty corner cases.

problems, including the fact that it doesn't work well with multi-line 
comments due to Ted's crazy table.  However, that could be fixed, and it
does work with single-line ones :).

a SourceLocation to get a RewriteBuffer, poke the RewriteBuffer

cleaner code.
