Add support for the llvm.unwind intrinsic, which we codegen to just do an abort
until we implement unwinding.
Add support for the invoke instruction, which codegens just like a call with
a branch after it.

The end effect of this change is that programs using the invoke instruction,
but never unwinding, will work fine.  Programs that unwind will abort until
we get unwind support.

Added/removed header file

Added an option to TableGen that allows users to specify a directory in which
to find include files.  TableGen will load include files from this directory if
it cannot find them in the current directory.
This feature was needed for building code inside the object tree (a la autoconf
style).
TODO: Allow for multiple -I options to specify a list of directories to search.

Cleaned up the code (spacing, not needed headers) and changed ostream function. Also made some functions inline.
