[committed] d: Use `int` to store class and struct flags

[Iain Buclaw via Gcc-patches]

Hi,

This patch replaces ClassFlags and StructFlags with an int.  In the D
implementation of the D front-end, this type has been changed to an
`enum class`.

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

Regards,
Iain
