[Dimitrios Apostolou <jimis at gmx dot net>]

Removed some leftover comments, used diff -p. Still doesn't work. 
Changelog (do I do this right?):

2011-07-24  Dimitrios Apostolou <jimis@gmx.net>

	* i386.c (ix86_live_on_entry),
	  mips.c (mips_extra_live_on_entry),
	  pa.h, pa.c (pa_extra_live_on_entry),
	  dce.c (dce_process_block, fast_dce),
	  df-problems.c (df_lr_local_compute, df_lr_confluence_0,
	df_lr_confluence_n, df_word_lr_local_compute, df_simulate_fixup_sets),
	  df-scan.c (df_scan_free_internal, df_scan_start_dump,
	df_scan_blocks, df_get_call_refs, df_bb_refs_collect,
	df_get_regular_block_artificial_uses, df_get_eh_block_artificial_uses,

	df_entry_block_bitmap_verify, df_scan_verify),
	  df.h, tm.texi, target.def, target.h, targhooks.c, targhooks.h:
	    Changed bitmaps that never map pseudo registers, to 
HARD_REG_SETs

	* hard-reg-set.h: added 
gcc_checking_assert (bit<FIRST_PSEUDO_REGISTER) for test, set and clear 
operations for HARD_REG_SETs.

	* df-problems.c: added bitmap_copy_from_hard_reg_set(), 
bitmap_ior_from_hard_reg_set()

	* df-core.c: added df_print_hard_reg_set()
