(delta) Reduced testcase
The S/390 movstr expander requires the target operand to be a
"register_operand". expand_movstr does not seem to respect this:
(define_expand "movstr"
[(set (reg:SI 0) (const_int 0))
(parallel
[(clobber (match_dup 3))
(set (match_operand:BLK 1 "memory_operand" "")
(match_operand:BLK 2 "memory_operand" ""))
(set (match_operand 0 "register_operand" "")
(unspec [(match_dup 1)
(match_dup 2)
(reg:SI 0)] UNSPEC_MVST))
(clobber (reg:CC CC_REGNUM))])]
...
With 4.4 the target operand is put into a register before expand_movstr is
invoked. I haven't looked into why that changed with 4.5 yet but from a first
glance I would say that this isn't a back-end problem.

More reduced testcase (fails with both -m31 -O0 and -m64 -O0 on the trunk):
extern char a[], *b[];
char *
foo (char *x, int y)
{
x = __builtin_stpcpy (x, b[a[y]]);
return x;
}

Untested fix. Andreas, could you please bootstrap/regtest this on s390* on the
trunk?
