[PATCH, i386]: Introduce QI_REGNO_P macro


Hello!

... to make a couple of trivial cleanups.

2012-08-04  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/i386.h (QI_REGNO_P): New define.
	(ANY_QI_REGNO_P): Ditto.
	(GENERAL_REGNO_P): Use IN_RANGE macro.
	(QI_REG_P): Use QI_REGNO_P.
	(ANY_QI_REG_P): Use GENERAL_REGNO_P and QI_REGNO_P.
	(HARD_REGNO_CALLER_SAVE_MODE): Use QI_REGNO_P.
	* config/i386/i386.c (ix86_hard_regno_mode_ok): Ditto.
	(x86_extended_QIreg_mentioned_p): Ditto.  Also check if
	register is a general register.

Tested on x86_64-pc-linux-gnu {,-m32} and committed to mainline SVN.

Uros.
