OpenMP: lvalue parsing for map clauses (C)
This patch adds support for parsing general lvalues ("locator list item
types") for OpenMP "map", "to" and "from" clauses to the C front-end,
similar to the previously-posted patch for C++.

gcc/c/
* c-pretty-print.cc (c_pretty_printer::postfix_expression,
c_pretty_printer::expression): Add OMP_ARRAY_SECTION support.
* c-parser.cc (c_parser_braced_init, c_parser_conditional_expression):
Don't allow OpenMP array section.
(c_parser_postfix_expression): Don't allow array section in statement
expression.
(c_parser_postfix_expression_after_primary): Add support
for OpenMP array section parsing.
(c_parser_expr_list): Don't allow OpenMP array section here.
(c_parser_omp_variable_list): Change ALLOW_DEREF parameter to
MAP_LVALUE. Support parsing of general lvalues in "map", "to" and
"from" clauses.
(c_parser_omp_var_list_parens): Change ALLOW_DEREF parameter to
MAP_LVALUE. Update call to c_parser_omp_variable_list.
(c_parser_oacc_data_clause): Update calls to
c_parser_omp_var_list_parens.
(c_parser_omp_clause_reduction): Use OMP_ARRAY_SECTION tree node
instead of TREE_LIST for array sections.
(c_parser_omp_target): Allow GOMP_MAP_ATTACH.
* c-tree.h (c_omp_array_section_p): Add extern declaration.
(build_omp_array_section): Add prototype.
* c-typeck.c (c_omp_array_section_p): Add flag.
(mark_exp_read): Support OMP_ARRAY_SECTION.
(build_omp_array_section): Add function.
(build_external_ref): Tweak error path for OpenMP array sections.
(handle_omp_array_sections_1): Use OMP_ARRAY_SECTION tree code instead
of TREE_LIST. Handle more kinds of expressions.
(c_oacc_check_attachments): Use OMP_ARRAY_SECTION instead of TREE_LIST
for array sections.
(c_finish_omp_clauses): Use OMP_ARRAY_SECTION instead of TREE_LIST.
Check for supported expression types.
