Added code to avoid checking for .bc when the filename is too short.

Renaming LLVM `dis' to `llvm-dis'.

Renaming LLVM `as' to `llvm-as'.

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.

Add test for the last chapter of our C++ exception handling odyssey.  llvmg++
now fully supports all C++ exception handling functionality.

* Add proper support for rethrown exceptions.
* 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.

New testcases, all of which work with llvmg++!
This tests exception specifications, and also adds an "easy" rethrow test.

Fix really nasty bugs in the CWriter, handling invoke instructions.  Tracking
these down was NOT phun.

Fix bug where we considered function types equivalent even if they had differing numbers of arguments
