New Revision: 124072

URL: http://llvm.org/viewvc/llvm-project?rev=124072&view=rev
Log:
Null initialize a few variables flagged by
clang's -Wuninitialized-experimental warning.
While these don't look like real bugs, clang's
-Wuninitialized-experimental analysis is stricter
than GCC's, and these fixes have the benefit
of being general nice cleanups.
