[PATCH] Fix PR18345: ldr= pseudo instruction produces incorrect code when using in inline assembly

[Rafael Ávila de Espíndola]

  I am still not completely sure I follow why the asm streamer should not print "ldr =...". It does print other pseudo instructions. In any case, that is some thing that is probably better discussed over another patch. This one is probably the right size for fixing the bug.

  LGTM with one nit: Please add a comment to the test explaining why this test is one of the few that needs "llc -filetype=obj".
