Fix checking of gimple types

* gengtype.c (struct seen_tag): New.

(mark_tag_as_seen): New.
(walk_subclasses): Support having multiple subclasses using the
same tag by tracking which tags have already been seen, and using
this to avoid adding duplicate cases to the "switch" statement.
The call to already_seen_tag introduces an O(N^2) when running
gengtype on N, the number of tags, due to the repeated linear
search, but currently max(N) is relatively small (the number of
GSS codes, which is 26).
(walk_type): Pass in a seen_tag for use by the walk_subclasses
recursion.

* gimple.def (GIMPLE_OMP_ATOMIC_STORE, GIMPLE_OMP_RETURN): Rename
underlying GSS values for these codes (from GSS_OMP_ATOMIC_STORE to
GSS_OMP_ATOMIC_STORE_LAYOUT) to make clear that although
GIMPLE_OMP_RETURN happens to share the data layout of
GIMPLE_OMP_ATOMIC_STORE, they are not otherwise related.
(GIMPLE_OMP_PARALLEL, GIMPLE_OMP_TARGET): Likewise, rename
underlying GSS value from GSS_OMP_PARALLEL to
GSS_OMP_PARALLEL_LAYOUT to make clear that these gimple codes are
not directly related; they merely share in-memory layout.
(GIMPLE_OMP_SINGLE, GIMPLE_OMP_TEAMS): Likewise, rename GSS values
for these two codes from GSS_OMP_SINGLE to GSS_OMP_SINGLE_LAYOUT.

* gsstruct.def (GSS_OMP_PARALLEL, gimple_statement_omp_parallel):

gimple_statement_eh_ctrl, with the invariant that
stmt->code == GIMPLE_EH_DISPATH.

(gimple_statement_omp_parallel): The existing class expressed
a layout (GSS_OMP_PARALLEL), but the codes with that layout
are not all related, so it makes more sense for this class to
express a *code* (GIMPLE_OMP_PARALLEL).  GSS_OMP_PARALLEL has
been renamed to GSS_OMP_PARALLEL_LAYOUT to express this, so
rename the existing gimple_statement_omp_parallel class to...
(gimple_statement_omp_parallel_layout): ...this, expressing
a statement of structure layout GSS_OMP_PARALLEL_LAYOUT.
(gimple_statement_omp_taskreg): New subclass of
gimple_statement_omp_parallel_layout, expressing the invariant
that the code is one of GIMPLE_OMP_PARALLEL or GIMPLE_OMP_TASK,
as used by the various gimple_omp_taskreg_ accessors.
(gimple_statement_omp_parallel): Reintroduce this class, this time
as a subclass of gimple_statement_omp_taskreg to express the
invariant stmt->code == GIMPLE_OMP_PARALLEL.
