Scalarize single-field-to-lclVar block copy

Morph has some logic to scalarize struct copies where the RHS is a scalar
and the LHS is a single-field struct.  This change adds the symmetric
logic where the LHS is a scalar and the RHS is a single-field struct.
This pattern shows up in Span<T> methods that initialize the data pointer
field, due to the way scalar replacement operates on spans.
