The result_type was not copied, resulting in a corrupted JMPZ_EX.
Fix can be verified by inspecting the opcodes of the following
function (it should not contain any _EX opcodes):
function test() {
if ($a && $b) {
echo "a";
}
if ($b || $c || $d) {
echo "b";
}
}

Warn on non-/bad numeric strings in arithmetic
This means we no longer allocate an unused VAR for the retval of
instructions that support unused results.
Nearly all instructions already used the result variable only if
it was used. The only exception to this was the return value
variable for internal function call results. I've adjusted the code
to use a stack zval for the unused return case now. As we have
retval specialization now, we know that it doesn't matter.
