[PATCH] Fix spelling of ones' complement.

[Marek Polacek]

Nitpicking time.  It's spelled "ones' complement" rather than "one's
complement".  I didn't go into config/.

Ok for trunk?

gcc/ChangeLog:

	* doc/implement-c.texi: Fix spelling.
	* doc/md.texi: Likewise.
	* expmed.c (emit_store_flag_int): Likewise.
	* optabs.c (expand_abs): Likewise.
	(expand_one_cmpl_abs_nojump): Likewise.
	* optabs.h (expand_abs): Likewise.
	* tree-ssa-ccp.c (gimple_nop_atomic_bit_test_and_p): Likewise.
