ee779cd4d6 Updated my entry as a test commit. 
Removed QMTest (it is long gone).
Acknowledge the fleeting'ness of my original autoconf work.
Mention that I fixed some bugs.

c6bdcfa8c0 Add new TargetLowering code to provide the final register type that an 
illegal value type will be transformed to, for code that needs the
register type after all transformations instead of just after the first
transformation.

Factor out the code that uses this information to do copy-from-regs and
copy-to-regs for various purposes into separate functions so that they
are done consistently.

370ff247c8 Add support for building with _GLIBCXX_DEBUG. New configure option 
--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time.  Currently it only
turns on _GLIBCXX_DEBUG.  Other expensive debugging checks added later
should be controlled by this configure option.

This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.
