Cuong Manh Le 326ea438bb cmd/compile: rewrite a, b = f() to use temporaries when type not identical
If any of the LHS expressions of an OAS2FUNC are not identical to the
respective function call results, escape analysis mishandles the
implicit conversion, causes memory corruption.

Instead, we should insert autotmps like we already do for f(g()) calls
and return g() statements.

Fixes #46725
