  Log Message:
  -----------
  [InlineAsm] Add support for address operands ("p").

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.
