Depends on when exactly it is done, there is the implicit declare target
discovery during gimplification, e.g. the var itself might not be initially
omp declare target but have its address used in some omp declare target
static var initializer or pragma omp declare target could appear as the last
one in the TU.
If it is always done after the whole TU was parsed and went through this
implicit declare target discovery, then I agree we could use
lookup_attribute, otherwise we can't.
