* Break apart saving and restoring registers into separate functions
* Instead of saving single and double FP registers, just save the double
  registers -- aliasing helps preserve the single FP registers as well.
* Request just as much memory for a stub as we actually use

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.

now fully supports all C++ exception handling functionality.

* Make catch_begin() produce a pointer that must be passed to catch_end()
* Eliminate the caught exception stack.
* Add optional debugging code that may be turned on.

This tests exception specifications, and also adds an "easy" rethrow test.

New testcase.  Unfortunately, native GCC gets this wrong.  Someday we will have to figure out how to deal with this.
