Some GCC tests such as gcc.c-torture/execute/simd-5.c fail on
powerpc-none-eabispe with an ICE in final_scan_insn (not optimizing) or
reload_cse_simplify_operands (optimizing).  This happens with trunk and 4.1
branch but not with 4.0 branch.  Reduced testcase:

typedef short Q __attribute__((vector_size(8)));

Q a, b, c;

void
f (void)
{
  c = a * b;
}

Non-optimizing:
t.c: In function 'f':
t.c:9: error: insn does not satisfy its constraints:
(insn 45 74 75 (set (reg:V4HI 0 0 [158])
        (mem/u/c/i:V4HI (lo_sum:SI (reg:SI 10 10)
                (symbol_ref/u:SI ("*.LC0") [flags 0x2])) [0 S8 A64])) 1059
{*movv4hi_internal} (nil)
    (nil))
t.c:9: internal compiler error: in final_scan_insn, at final.c:2379
