Fix "PR c++/91073 if constexpr no longer works directly with Concepts."
This is a rather serious regression, filed in July 2019. Luckily the
fix is simple: is localized to parser.c and cp-tree.h in cp and boils
down to only a few lines.
Testing OK on x86_64-linux. Approved off-line by Jason Merrill.

* cp-tree.h (is_constrained_auto): New.
* parser.c (cp_parser_maybe_commit_to_declaration): Correctly
handle concept-check expressions; take a cp_decl_specifier_seq*
instead of a bool.
(cp_parser_condition): Update call.
(cp_parser_simple_declaration): Likewise.
(cp_parser_placeholder_type_specifier): Correctly handle
concept-check expressions.
