[Bug inline-asm/34832] New: rejects "i"(static_const_var) without -O2

["stsp at users dot sourceforge dot net" <gcc-bugzilla at gcc dot gnu dot org>]

Hi.

Opening per suggestion in Bug 23200.

The following program:
---
int main()
{
    static const int i = 1;
    asm volatile ("" :: "i"(i));
    return i;
}
---

gives this when compiled without -O2:
---
asc1.c: In function 'main':
asc1.c:4: warning: asm operand 0 probably doesn't match constraints
asc1.c:4: error: impossible constraint in 'asm'
---

Using -O2 makes it to compile.
