* config/mcore/mcore-protos.h (mcore_r15_operand_p): Declare.
	(mcore_secondary_reload_class): Declare.
	(mcore_output_inline_const_forced): Remove.
	* config/mcore/mcore.md (movsi): Remove the code that forced
	non-inlineable constants into a register if the target was r15
	or the stack pointer.  Remove constant restrictions from the main
	define_insn.  Remove r <- I, r <- M and r <- N alternatives in favor
	of an r <- P alternative.  Remove fallback define_insn for reload.
	(movhi, movqi): Use gen_lowpart rather than gen_SUBREG.  Remove reload
	define_insn.  Use mcore_output_move in the remaining define_insn.
	Adjust condition and constraints in the way as for movsi.
	(movdi): Always split unacceptable constants into two.  Use
	simplify_gen_subreg instead of operand_subword{,_force}.
	* config/mcore/mcore.c (mcore_output_inline_const_forced): Remove.
	(mcore_output_move): Support HImode and QImode moves as well.
	(mcore_m15_operand_p): New function.
	(mcore_reload_class): Use it to detect cases where LRW_REGS are better.
	(mcore_secondary_reload_class): New function.
	* config/mcore/mcore.h (SECONDARY_RELOAD_CLASS): Redefine in
	terms of mcore_secondary_reload_class.
