when the unconditional branch destination is the fallthrough block. The
canonicalization makes it easier to allow optimizations on DAGs to invert
conditional branches. The branch folding pass (and AnalyzeBranch) will clean up
the unnecessary unconditional branches later.

This is one of the patches leading up to disabling codegen prepare critical edge
splitting.

Refactor GRExprEngine::VisitCall() to use EvalArguments(), just like VisitCXXMemberCallExpr().  Ideally we should unify these code paths as much as possible, since they only differ by a few details.

Moved the PBQP allocator class out of the header and back in to the cpp file to hide the gory details.
Allocator instances can now be created by calling createPBQPRegisterAllocator.

Tidied up use of CoalescerPair as per Jakob's suggestions.

Made the new PBQPBuilder based construction process the default. The internal construction process
remains in-place and available via -pbqp-builder=false for now. It will be removed shortly if the new
process doesn't cause any regressions.

 - Sema is now exported (and there was much rejoicing.)

 - Storage classes are now centrally defined.

Also fixed some bugs that the new LLVM picked up.

because of the lack of a newline, AsmToken::Eof
was being found instead of AsmToken::EndOfStatement.

 - Therefore, we can lower out the NEON wrapper structs and pass the vectors
   directly. This makes a huge difference in the cleanliness of the IR after
   optimization.
 - I will trust, but verify, via future ABITest testing (for APCS-GNU, at
   least).

new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.

into python-extensions.swig, which gets included into lldb.swig, and
adds them back into the classes when swig generates it's C++ file.  This
keeps the Python stuff out of the general API classes.

Also fixed a small bug in the copy constructor for SBSymbolContext.

actually test-and-compare anything yet.  The lldbtest.TestBase has an added
method setTearDownCleanup(dictionary=None) to facilitate running the cleanup
right after each data type test is run.  The test case can pass a dictionary
object when registering the test case cleanup.

There is currently only int_type test in the repository.

CombineTo to avoid putting the result on the worklist.  I don't think it makes
much difference for now, but it might help someday as we add more DAG
combine optimizations.

good thing to do.

truncates are free only in the case where the extended type is legal but the
load type is not.  If both types are illegal, such as when they are too big,
the load may not be legalized into an extended load.
