i386.h (FIXED_REGISTERS): Do not mark REX registers here.
* 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.
