Environment hasn't been uniqued in a FoldingSet for some time, so this
was just wasting a pointer in GRState.

GRState object has a direct reference to its GRStateManager, making
the functionality of GRStateRef redunandant.  This will lead to some
nice API cleanup and code shrinking across libAnalysis.

 - Make python test runner force COLUMNS=0 to increase determinism.

 - Substitute clang-cc as we do for clang.

 - Improved detection of Ctrl-C.

 - Honor CLANG and CLANGCC environment variables.

 - Add proper command line arguments to TestRunner.py (see --help)

We need to use double-checked locking for lazy initialization in this case when running multithreaded.

move loads back past a check that the load address
is valid, see new testcase.  The test that went
in with 72661 has exactly this case, except that
the conditional it's moving past is checking
something else; I've settled for changing that
test to reference a global, not a pointer.  It
may be possible to scan all the tests you pass and
make sure none of them are checking any component
of the address, but it's not trivial and I'm not
trying to do that here.

Add an RAII ScopedWriter, which allows one to acquire a writer lock for the duration of a scope.  Simplify a lot of uses of
writer locks in Constants.cpp by using it.

Simplify the locking on the Constants tables, and make it more efficient, by pushing it into the ValueMap from the callers.
Document those ValueMap functions that are _not_ locked, so that callers are aware that they need to do the locking themselves.

Type safety for Constants.cpp!  Some of this is temporary, as I'm planning to push some of the R/W locking into FoldingSet.

Make sure that .td and .def files get into the list of headers in a CMake build, for use in Xcode and Visual Studio

We need to guard reads of the AbstractTypeUsers list, as well as writes to it.  While it would be nice to use a R/W lock here,
we can't, because it HAS to be recursive.
