Detailed Description

Perform Scalarization (= Argument simplification).

This means that, e.g.,

f := λ (x_1:[T_1, T_2], .., x_n:T_n).E

will be transformed to

f' := λ (y_1:T_1, y_2:T_2, .. y_n:T_n).E[x_1 \ (y_1, y_2); ..; x_n \ y_n]

if f appears in callee position only (see EtaExp). It will not flatten mutable Sigmas or Arrays.
