* sysdeps/i386/bp-asm.h (PCOFF): New constant.
(POP_ERRNO_LOCATION_RETURN): Fold insns.
* sysdeps/i386/bits/setjmp.h (JB_SIZE): New constant.
(PUSH_SIGNAL_MASK): New macro.
* sysdeps/i386/__longjmp.S (__longjmp): Wrap symbol in BP_SYM ().
LEAVE is unnecessary. Check bounds of jmp_buf.
* sysdeps/i386/elf/setjmp.S: Call PUSH_SIGNAL_MASK. Wrap symbols
in BP_SYM (). Check bounds of jmp_buf. Don't call LEAVE until
immediately before tail-call.
* sysdeps/i386/setjmp.S: Likewise.
* sysdeps/i386/bsd-_setjmp.S: Likewise.
* sysdeps/i386/bsd-setjmp.S: Likewise.
