i386/bits/syscalls.h: generate better code using more restrictive asm constraints
Example: time() doesn't push/pop two registers now, and is smaller:
<__GI_time>:
-57 push %edi
-8b 7c 24 08 mov 0x8(%esp),%edi
-53 push %ebx
-89 fb mov %edi,%ebx
+8b 4c 24 04 mov 0x4(%esp),%ecx
+87 cb xchg %ecx,%ebx
b8 0d 00 00 00 mov $0xd,%eax
cd 80 int $0x80
-5b pop %ebx
-5f pop %edi
+87 cb xchg %ecx,%ebx
c3 ret
