Add INLINE_SYSCALL_ERROR_RETURN_VALUE
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_ERROR_RETURN_VALUE so that i386 can optimize setting
errno by branching to the internal __syscall_error without PLT.
With i386 INLINE_SYSCALL_ERROR_RETURN_VALUE 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:

Since version 2.1 the return value of a system call might be

negative even if the call succeeded. E.g., the `lseek' system call

for < 0, but test for a real error by making sure the value in R0

is a real error number. Linus said he will make sure the no syscall

returns a value in -1 .. -4095 as a valid result so we can savely

[__ia64__] (TLS_LE, TLS_IE): Fix typos. Add ;; at start of asm if
gp is used early.
[__ia64__] (TLS_LD, TLS_GD): Likewise. Use __TLS_CALL_CLOBBERS.
* elf/Makefile ($(objpfx)tst-tlsmod5.so, $(objpfx)tst-tlsmod6.so):
Ensure libc.so in DT_NEEDED.

CHECK_STATIC_TLS before l_tls_offset use.

TLS_INIT_TP_EXPENSIVE is not defined, allocate even if no PT_TLS
segment has been found. If TLS_DTV_AT_TP, allocate TLS_PRE_TCB_SIZE
bytes below result and add tcb_offset to memsz.
