PR rtl-optimization/42575
* dce.c (word_dce_process_block): Renamed from byte_dce_process_block.
Argument AU removed. All callers changed. Ignore artificial refs.
Use return value of df_word_lr_simulate_defs to decide whether an insn
is necessary.
(fast_dce): Rename arg to WORD_LEVEL.
(run_word_dce): Renamed from rest_of_handle_fast_byte_dce. No longer
static.
(pass_fast_rtl_byte_dce): Delete.
* dce.h (run_word_dce): Declare.
* df-core.c (df_print_word_regset): Renamed from df_print_byteregset.
All callers changed. Simplify code to only deal with two-word regs.
* df.h (DF_WORD_LR): Renamed from DF_BYTE_LR.
(DF_WORD_LR_BB_INFO): Renamed from DF_BYTE_LR_BB_INFO.
(DF_WORD_LR_IN): Renamed from DF_BYTE_LR_IN.
(DF_WORD_LR_OUT): Renamed from DF_BYTE_LR_OUT.
(struct df_word_lr_bb_info): Renamed from df_byte_lr_bb_info.
(df_word_lr_mark_ref): Declare.
(df_word_lr_add_problem, df_word_lr_mark_ref, df_word_lr_simulate_defs,
df_word_lr_simulate_uses): Declare or rename from byte variants.
(df_byte_lr_simulate_artificial_refs_at_top,
df_byte_lr_simulate_artificial_refs_at_end, df_byte_lr_get_regno_start,
df_byte_lr_get_regno_len, df_compute_accessed_bytes): Delete
declarations.
(df_word_lr_get_bb_info): Rename from df_byte_lr_get_bb_info.
(enum df_mm): Delete.
* df-byte-scan.c: Delete file.
* df-problems.c (df_word_lr_problem_data): Renamed from
df_byte_lr_problem_data, all members deleted except for
WORD_LR_BITMAPS, which is renamed from BYTE_LR_BITMAPS. Uses changed.
(df_word_lr_expand_bitmap, df_byte_lr_simulate_artificial_refs_at_top,
df_byte_lr_simulate_artificial_refs_at_end, df_byte_lr_get_regno_start,
df_byte_lr_get_regno_len, df_byte_lr_check_regs,
df_byte_lr_confluence_0): Delete functions.
(df_word_lr_free_bb_info): Renamed from df_byte_lr_free_bb_info; all
callers changed.
(df_word_lr_alloc): Renamed from df_byte_lr_alloc; all callers changed.
Don't initialize members that were deleted, don't try to discover data
about registers. Ignore hard regs.
(df_word_lr_reset): Renamed from df_byte_lr_reset; all callers changed.
(df_word_lr_mark_ref): New function.
(df_word_lr_bb_local_compute): Renamed from
df_byte_bb_lr_local_compute; all callers changed. Use
df_word_lr_mark_ref. Assert that artificial refs don't include
pseudos. Ignore hard registers.

Assert that exit block uses don't contain pseudos.
(df_word_lr_init): Renamed from df_byte_lr_init; all callers changed.
(df_word_lr_confluence_n): Renamed from df_byte_lr_confluence_n; all
callers changed. Ignore hard regs.

confluence operator 0 set to NULL.
(df_word_lr_add_problem): Renamed from df_byte_lr_add_problem; all
callers changed.
(df_word_lr_simulate_defs): Renamed from df_byte_lr_simulate_defs.
Return bool, true if bitmap changed or insn otherwise necessary.
