making the new LVI stuff smart enough to subsume some special
cases in the old code.  Disable them when LVI is around, the
testcase still passes.

constant constraints.  Improve the LVI lattice to include inequality 
constraints.

Enhance Checker class (and GRExprEngine) to support PostVisitation for CallExprs.  No clients (yet).

MachineBasicBlock so other passes can utilize it.

Revert 86857. It's causing consumer-typeset to fail, and there's a better way to do it forthcoming anyway.

Add a test to make sure we don't create extraneous stubs.

Fixed an iteration condition in PreAllocSplitting. This should fix some miscompilations casued by PreAllocSplitting.

This allows StringRef to skip controversial if(str) check in constructor.
Buildbots, wait for corresponding clang and llvm-gcc FE check-ins!

When building a template-id type, check whether the template-name

handle it as a template-id type.
