This patch adds support for inline assembly address operands using the "p" constraint on X86 and SystemZ. This was in fact broken on X86 (see example at https://reviews.llvm.org/D110267, Nov 23). These operands should probably be treated the same as memory operands by CodeGenPrepare, which have been commented with "TODO" there.
