Subject: [PATCH 1/3] Add INLINE_SYSCALL_RETURN/INLINE_SYSCALL_ERROR_RETURN

For ia32 PIC, the first thing of many syscalls does is to call
__x86.get_pc_thunk.reg to load PC into reg in case there is an error,
which is required for setting errno.  In most cases, there are no
errors.  But we still call __x86.get_pc_thunk.reg.  This patch adds
INLINE_SYSCALL_RETURN and INLINE_SYSCALL_ERROR_RETURN so that i386
can optimize setting errno by branching to the internal __syscall_error
without PLT.

INLINE_SYSCALL_ERROR_RETURN is designed to take the negative error
number returned from the majority of Linux kernels for which negating
is a no-op with INTERNAL_SYSCALL_ERRNO.

With i386 INLINE_SYSCALL_RETURN, INLINE_SYSCALL_ERROR_RETURN and
i386 syscall inlining optimization for GCC 5, for
sysdeps/unix/sysv/linux/fchmodat.c with -O2 -march=i686
-mtune=generic, GCC 5.2 now generates:

<fchmodat>:
   0:	push   %ebx
   1:	mov    0x14(%esp),%eax
