[committed] d: Get __c_wchar_t type from build_frontend_type

[Iain Buclaw]

Hi

This patch uses build_frontend_type to get the underlying type for
__c_wchar_t.  The previous field has been removed from the upstream D
implementation of the D front-end.

Bootstrapped and regression tested on x86_64-linux-gnu/-m32/-mx32,
committed to mainline.

Regards,
Iain
