Confirmed.
sse.md includes a named pattern defined with non-conforming operands:
(define_expand "float<floatunssuffix>v2div2sf2"
[(set (match_operand:V4SF 0 "register_operand" "=v")
(vec_concat:V4SF
(any_float:V2SF (match_operand:V2DI 1 "nonimmediate_operand" "vm"))
(match_dup 2)))]
"TARGET_AVX512DQ && TARGET_AVX512VL"
"operands[2] = CONST0_RTX (V2SFmode);")
V2SF vectorization now triggers this expander.

Adjusted testcase, so that there is no UB.
void bar (void);
void
foo (long int *x, int y, int *z, int v)
{
int a[y];
int b;
for (b = 0; b < 3; ++b)
z[b] = x[b] + 1.0f;
if (v)
return;
bar ();
}

Interesting. I've done quite a bit of cooperlake specific testing and
found some bugs in gcc trunk.
AFAIK cooperlake is recent Intel. Is there a newer -march
setting I could usefully test or is cooperlake recent enough ?
Also, AFAIK Zen version 2 is a recent AMD -march setting.
Is there a newer AMD -march setting I could usefully test ?
A complete compile of Fedora Linux, with about 6,700 packages,
seems to be a good testcase for recent gcc trunk.
