Sean Callanan cf5498f1c7 Added a temporary hack to allow casting of Objective-C 
method results to int.  This will only last until we
get accurate type information for Objective-C methods
or some way of making their types inferred by the
parser.

Andrew Trick 1c24605a57 This is a prototype of an experimental register allocation 
framework. It's purpose is not to improve register allocation per se,
but to make it easier to develop powerful live range splitting. I call
it the basic allocator because it is as simple as a global allocator
can be but provides the building blocks for sophisticated register
allocation with live range splitting. 

A minimal implementation is provided that trivially spills whenever it
runs out of registers. I'm checking in now to get high-level design
and style feedback. I've only done minimal testing. The next step is
implementing a "greedy" allocation algorithm that does some register
reassignment and makes better splitting decisions.

Jakob Stoklund Olesen 4cf8fe31bb Be more strict about detecting multi-use blocks for isolation. 
When a block has exactly two uses and the register is both live-in and live-out,
don't isolate the block. We would be inserting two copies, so we haven't really
made any progress.

If the live-in and live-out values separate into disconnected components after
splitting, we would be making progress. We can't detect that for now.

Douglas Gregor c0d2490ac4 In the presence of using declarations, we can find the same class 
members in class subobjects of different types. So long as the
underlying declaration sets are the same, and the declaration sets
involve non-instance members, this is not an ambiguity.

Ted Kremenek 5c97605c1d Fix a horrible bug in all dataflow analyses that use CFGRecStmtVisitor (including live variables analysis). 
We shouldn't recurse into CompoundStmts since they are already inlined in the CFG.  This could result in
bogus dead stores warnings (among other things).

John McCall 457a04e3ce Substantially revise how clang computes the visibility of a declaration to 
more closely parallel the computation of linkage.  This gets us to a state
much closer to what gcc emits, modulo bugs, which will undoubtedly arise in
abundance.

Jakob Stoklund Olesen 2d60075590 Be more strict when detecting critical edges before loop splitting. 
An exit block with a critical edge must only have predecessors in the loop, or
just before the loop. This guarantees that the inserted copies in the loop
predecessors dominate the exit block.
