cmd/compile: ensure interface-to-concrete comparison panics when it should
In interface-to-concrete comparisons, we are short circuiting on the interface
value's dynamic type before evaluating the concrete expression for side effects,
causing concrete expression won't panic at runtime, while it should.
To fix it, evaluating the RHS of comparison before we do the short-circuit.
We also want to prioritize panics in the LHS over the RHS, so evaluating
the LHS too.
Fixes #32187
