@ FIXME: LDR (literal)
@------------------------------------------------------------------------------
@ label operands currently assert the show-encoding asm comment helper due
@ to the use of non-contiguous bit ranges for fixups in ARM. Once that's
@ cleaned up, we can write useful assembly testcases for these sorts of
@ instructions.
