[committed] d: Use toStringExp instead of explicit cast

[Iain Buclaw via Gcc-patches]

Hi,

This patch replaces uses of casting to StringExp with toStringExp.

Bootstrapped and regression tested on x86_64-linux-gnu, and committed to
master.

Regards
Iain


gcc/d/ChangeLog:

        * d-attribs.cc (build_attributes): Use toStringExp instead of cast.
        * toir.cc (IRVisitor::visit): Likewise.
