Fun x86 encoding tricks: when adding an immediate value of 128,
...
use a SUB instruction instead of an ADD, because -128 can be
encoded in an 8-bit signed immediate field, while +128 can't be.
This avoids the need for a 32-bit immediate field in this case.
A similar optimization applies to 64-bit adds with 0x80000000,
with the 32-bit signed immediate field.
To support this, teach tablegen how to handle 64-bit constants.

Add support for Canadian Cross builds where the host executables are not
...
runnable on the build machine.
There are a few bits that need built for the build environment (TableGen).
This patch builds those bits, and the associated libraries, for the build
environment as well as the (usual) host environment.
Thanks to Eric C. and Devang P. for pre-commit review.

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.
