YJIT: Fix argument clobbering in some block_arg+rest_param calls (#8647)
Previously, for block argument callsites with some specific argument
count and callee local variable count combinations, YJIT ended up
writing over arguments that are supposed to be collected into a rest
parameter array unmodified.
Detect when clobbering would happen and avoid it. Also, place the block
handler after the stack overflow check, since it writes to new stack
space.
