[GCC-14][committed] d: Fix ICE in expand_d_format when diagnosing empty enum [PR117115]

[Iain Buclaw]

Hi,

This patch backports the individual fix for PR117115 from the upstream
merge in r15-6824 into the releases/gcc-14 branch.

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

Regards,
Iain.
