[committed] d: Convert convert_for_rvalue switch statement into if condition

[Iain Buclaw <ibuclaw@gdcproject.org>]

Hi,

This patch replaces the switch statement in convert_for_rvalue with an
if condition.  In the D implementation of the D front-end, the condition
value has been changed to an `enum class` type.

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

Regards,
Iain
