YJIT: Fix autosplat miscomp for blocks with optionals

When passing an array as the sole argument to `yield`, and the yieldee
takes more than 1 optional parameter, the array is expanded similar
to `*array` splat calls. This is called "autosplat" in
`setup_parameters_complex()`.

Previously, YJIT did not detect this autosplat condition. It passed the
array without expanding it, deviating from interpreter behavior.
Detect this conditon and refuse to compile it.
