We only needed the statement list as aid during the gimplify.cc handling
of GOMP_alloc/GOMP_free for Fortran. How about just remove_attribute it
in that case? As discussed, as DECL_ATTRIBUTE gets added from the left
to the DECL_CHAIN, there shouldn't be a problem of introducing shared
trees; note that 'omp allocate' itself is added per DECL, i.e. it does
not introduce sharing itself, either.

Tested with x86-64-gnu-linux.
