More infrastructure to avoid bogus RTL on H8.
Continuing the work to add constraints to avoid invalid RTL
with autoinc addressing modes. Specifically this patch adds
the memory constraints similar to the pdp11.
gcc/
* config/h8300/constraints.md (Za..Zh): New constraints for
autoinc addresses using a specific register.
* config/h8300/h8300.cc (pre_incdec_with_reg): New function.
* config/h8300/h8300-protos.h (pre_incdec_with_reg): Add prototype.
