cmd/compile: do not use special literal assignment if LHS is address-taken
A composite literal assignment
x = T{field: v}
may be compiled to
x = T{}
x.field = v
We already do not use this form is RHS uses LHS. If LHS is
address-taken, RHS may uses LHS implicitly, e.g.
v = &x.field
x = T{field: *v}
The lowering above would change the value of RHS (*v).
Fixes #52953.
