[m32c] m32c.cpu tweaks


This completes the implementation of LDE and STE, and fixes some
mismatched modes for other opcodes.  Committed.

[cpu]

	* m32c.cpu (lde, ste): Add dsp[a0] and [a1a] addressing.
	(indexb, indexbd, indexbs, indexw, indexwd, indexws, indexl,
	indexld, indexls): .w variants have `1' bit.
	(rot32.b): QI, not SI.
	(rot32.w): HI, not SI.
	(xchg16): HI for .w variant.

[opcodes]

	* m32c-asm.c: Regenerate.
	* m32c-desc.c: Regenerate.
	* m32c-desc.h: Regenerate.
	* m32c-dis.c: Regenerate.
	* m32c-ibld.c: Regenerate.
	* m32c-opc.c: Regenerate.
	* m32c-opc.h: Regenerate.
