Ah yes, I'd forgotten that the instruction sequence is still largely
decided in X86ISelLowering.cpp.

You should start by tweaking the LowerConstantPool function. But that
seems to cause an ISel failure that you'll have to investigate
(something isn't expecting to have to deal with RIP relative accesses
in Large code model).
