[PATCH, ARM] Fix generation of LDRD/STRD on Thumb-2

This patch fixes a bug in the Thumb-2 code generation where we would
incorrectly generate two 32-bit load instructions.  Because of the
different offset ranges, in addition to being less efficient, this
generated code that would not always assemble.

	* arm.c (output_move_double): Don't synthesize thumb-2 ldrd/strd with
	two 32-bit instructions.
