Log:
	* config/i386/i386.h (FIXED_REGISTERS): Do not mark REX registers here.
	(CALL_USED_REGISTERS): Use bitmaps to mark call-used registers
	for different ABIs.
	(enum reg_class): Move CLOBBERED_REGS just before GENERAL_REGS.
	(REG_CLASS_NAMES): Update.
	(REG_CLASS_CONTENTS): Update.  Clear CLOBBERED_REGS members.
	* config/i386/i386.c (ix86_conditional_register_usage): Disable
	REX registers on 32bit targets.  Handle bitmaps from
	CALL_USED_REGISTERS initializer.  Calculate CLOBBERED_REGS register
	set from GENERAL_REGS also for 32bit targets.  Do not change call
	used register set for TARGET_64BIT_MS_ABI separately.
