Keep track of the last instruction to define each register individually
instead of per DomainValue.  This lets us track more accurately when a
register was last written.

Also track register ages across basic blocks.  When entering a new
basic block, use the least stale predecessor def as a worst case
estimate for register age.

The register age is used to arbitrate between conflicting domains. The
most recently defined register wins.

Fix potential memory leak for clients of clang_getOverriddenCursors().  If the number of overriden cursors is 0, do not allocate an array of CXCursors.  This fixes a memory leak in c-index-test, and clients who use this API in a similar way.

This is a partial revert of r143846. While cleaning up after a crash is
probably a good idea, we were also deleting .d files if the compilation failed
due to invalid input, which is not the desired behavior. The test is XFAIL'd
until the cleanup code can be reworked to do the right thing.

These annotations are disabled entirely when either ENABLE_THREADS is off, or
building a release build. When enabled, they add calls to functions with no

Use these annotations to inform tsan that the race used inside ManagedStatic
initialization is actually benign. Thanks to Kostya Serebryany for helping
