Backport from mainline:

PR target/13373
* 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.
