2016-09-19 Andre Vehreschild

- expr.c (gfc_check_assign): Added flag to control whether datatype conversion is allowed.
- gfortran.h: Added caf-token-tree to gfc_component. Changed prototypes mostly to add whether datatype conversion is allowed.
- gfortran.texi: Added documentation for the caf_reference_t and the caf_*_by_ref function.
- primary.c (caf_variable_attr): Similar to gfc_variable_attr but focused on the needs of coarrays. (gfc_caf_attr): Same.
- resolve.c (resolve_ordinary_assign): Set the conversion allowed flag when not in a coarray.
- trans-array.c (gfc_array_init_size): Moved setting of array descriptor's datatype before the alloc, because caf_register needs it. (gfc_array_allocate): Changed notion of whether an array is a coarray. (gfc_array_deallocate): Same. (gfc_alloc_allocatable_for_assignment): Added setting of coarray's array descriptor datatype before the register. And using deregister/ register to mimmick a realloc for coarrays.
- trans-decl.c (gfc_build_builtin_function_decls): Corrected signatures of old caf-functions and added signature definitions of the _by_ref ones. (generate_coarray_sym_init): Adapted to new caf_register signature.
- trans-expr.c (gfc_conv_scalar_to_descriptor): Make sure a constant is translated to an lvalue expression before use in an array descriptor. (gfc_get_ultimate_alloc_ptr_comps_caf_token): New function. Get the last allocatable component's coarray token. (gfc_get_tree_for_caf_expr): For top-level object get the coarray token and check for unsupported features. (gfc_get_caf_token_offset): Getting the offset might procude new statements, which now are stored in the pre and post of the current se. (gfc_caf_get_image_index): For this image return a call to caf_this_image. (expr_may_alias_variables): Check that the result is set for testing its properties. (alloc_scalar_allocatable_for_assignment): Added auto allocation of coarray components. (gfc_trans_assignment_1): Rewrite an assign to a coarray object to be a sendget.
- trans-intrinsic.c (conv_caf_vector_subscript_elem): Corrected wrong comment. (compute_component_offset): Compute the correct offset a structure member. (conv_expr_ref_to_caf_ref): Convert to a chain of refs into caf_references. (gfc_conv_intrinsic_caf_get): Call caf_get_by_ref instead of caf_get. (conv_caf_send): Call caf_*_by_ref for coarrays that need reallocation. (gfc_conv_intrinsic_function): Adapted to new signuature of the caf drivers. (conv_intrinsic_atomic_op): Add pre and post statements correctly. (conv_intrinsic_atomic_ref): Same. (conv_intrinsic_atomic_cas): Same. (conv_intrinsic_event_query): Same.
- trans-stmt.c (gfc_trans_lock_unlock): Same. (gfc_trans_event_post_wait): Same. (gfc_trans_allocate): Support allocation of allocatable coarrays. (gfc_trans_deallocate): And there deallocation.
- trans-types.c (gfc_typenode_for_spec): Added flag to control whether a component is part of coarray. When so, then add space to store a coarray token. (gfc_build_array_type): Same. (gfc_get_array_descriptor_base): Same. (gfc_get_array_type_bounds): Same. (gfc_sym_type): Same. (gfc_get_derived_type): Same. (gfc_get_caf_reference_type): Declare the caf_reference_type.
- trans-types.h: Prototype changes only.
- trans.c (gfc_allocate_using_lib): Use the updated caf_register signature. (gfc_allocate_allocatable): Same. (gfc_deallocate_with_status): Same.
- trans.h: Defined the runtime types for caf_reference_t and the enums.
