ATTRIBUTE_UNUSED on used arguments...

[François-Xavier Coudert]

While reading through iresolve.c, I noticed two uses of
ATTRIBUTE_UNUSED on a argument that seems to be used. As I don't want
to do anything stupid and I might be missing an obvious point here,
I'm asking for someone to give it a quick look: they are in functions
gfc_resolve_cpu_time and gfc_resolve_random_number.

I plan to commit the following patch after someone can confirm that it
isn't completely stupid:
