What a weird instruction.

cceba83893 MC/AsmParser: Add support for 'a + 4@GOTPCREL' and friends, by reconsing the
expression to include the modifier.
 - Gross, but this a corner case we don't expect to see often in practice, but
   it is worth accepting.
 - Also improves diagnostics on invalid modifiers.

c5cebeb3cb "sldt <mem>" is ambiguous in 64-bit mode, but should
