Drop original H8/300 support. This should generate identical code for the remaining subtargets. Defaults to H8/300H codegen
* config/h8300/constraints.md (L and N): Simplify now that we're not
longer supporting the original H8/300 chip.
* config/h8300/elf.h (LINK_SPEC): Likewise. Default to H8/300H.
* config/h8300/h8300.c (shift_alg_qi): Drop H8/300 support.
(shift_alg_hi, shift_alg_si): Similarly.
(h8300_option_overrides): Similarly. Default to H8/300H. If
compiling for H8/S, then turn off H8/300H. Do not update the
shift_alg tables for H8/300 port.
(h8300_emit_stack_adjustment): Remove support for H8/300. Simplify
where possible.
(push, split_adds_subs, h8300_rtx_costs): Likewise.
(h8300_print_operand, compute_mov_length): Likewise.
(output_plussi, compute_plussi_length): Likewise.
(compute_plussi_cc, output_logical_op): Likewise.
(compute_logical_op_length, compute_logical_op_cc): Likewise.
(get_shift_alg, h8300_shift_needs_scratch): Likewise.
(output_a_shift, compute_a_shift_length): Likewise.
(output_a_rotate, compute_a_rotate_length): Likewise.
(output_simode_bld, h8300_hard_regno_mode_ok): Likewise.
(h8300_modes_tieable_p, h8300_return_in_memory): Likewise.
* config/h8300/h8300.h (TARGET_CPU_CPP_BUILTINS): Likewise.
(attr_cpu, TARGET_H8300): Remove.
(TARGET_DEFAULT): Update.
(UNITS_PER_WORD, PARM_BOUNDARY): Simplify where possible.
(BIGGEST_ALIGNMENT, STACK_BOUNDARY): Likewise.
(CONSTANT_ADDRESS_P, MOVE_MAX, Pmode): Likewise.
(SIZE_TYPE, POINTER_SIZE, ASM_WORD_OP): Likewise.
* config/h8300/h8300.md: Simplify patterns throughout.
* config/h8300/t-h8300: Update multilib configuration.
