RuntimeDyld: override EH frame registration with trivial version.

Browse Source 
llvm-rtdyld was relying on the default memory manager's EH frame registration,
which is host-dependent rather than target-dependent. As a result, big-endian
ELF Mips EH frames were being registered on OS X (and elsewhere). This is a
really bad idea.
