	* mini-exceptions.c (mono_resume_unwind): New function to resume unwinding at the
	end of an LLVM compiled finally clause.
	(mono_handle_exception_internal): Save the exception handling state in TLS
	before calling an LLVM compiled finally clause, so mono_resume_unwind () can
	resume unwinding from that point.

	* unwind.c (mono_unwind_get_ops_from_fde): Rename this to
	mono_unwind_decode_fde, decode the Language Specific Data Area (LSDA) too,
	to obtain the addresses of the exception handling regions.

	* mini-llvm.c: Add beginnings of support for exception handling, currently only
	finally clauses are supported.

	* mini.c (mini_method_compile): Add support for LLVM code with exception
	handlers.
