* trans-stmt.c (forall_info): Remove pmask field.
(gfc_trans_forall_loop): Remove NVAR argument, instead assume that
NVAR covers all the interation variables in the current forall_info.
Add an extra OUTER parameter, which specified the loop header in
which to place mask index initializations.
(gfc_trans_nested_forall_loop): Remove NEST_FLAG argument.
Change the semantics of MASK_FLAG to only control the mask in the
innermost loop.
(compute_overall_iter_number): Optimize the trivial case of a
top-level loop having a constant number of iterations. Update
call to gfc_trans_nested_forall_loop. Calculate the number of
times the inner loop will be executed, not to size of the
iteration space.
(allocate_temp_for_forall_nest_1): Reuse SIZE as BYTESIZE when
sizeof(type) == 1. Tidy up.
(gfc_trans_assign_need_temp): Remove NEST_FLAG argument from calls
to gfc_trans_nested_forall_loop.
(gfc_trans_pointer_assign_need_temp): Likewise.
(gfc_trans_forall_1): Remove unused BYTESIZE, TMPVAR, SIZEVAR and
LENVAR local variables. Split mask allocation into a separate
hunk/pass from mask population. Use allocate_temp_for_forall_nest
to allocate the FORALL mask with the correct size. Update calls
to gfc_trans_nested_forall_loop.
(gfc_evaluate_where_mask): Update call to
gfc_trans_nested_forall_loop.
(gfc_trans_where_2): Likewise.
* gfortran.dg/forall_6.f90: New test case.
* gfortran.dg/dependency_8.f90: Update test to find "temp" array.
* gfortran.dg/dependency_13.f90: Likewise.
