Completely rework how we handle X constrained labels for inline asm.

X should really be treated as i. Then existing tests can be moved to use
i D115410 <https://reviews.llvm.org/D115410> and clang can just emit i D115311 <https://reviews.llvm.org/D115311>. (D115410 <https://reviews.llvm.org/D115410> and D115311 <https://reviews.llvm.org/D115311> are
callbr, but this can be done for label inputs, too).
