Hmm, I'm uncomfortable with this change; not all errors lead to
unwinding the whole declaration context. Typically they just mean
we're changing from one tentative parse to another. If for instance
you had a function with one generic parameter and one with a type
like
A<42>, we would try to parse 42 as a type and hit cp_parser_error
before parsing it as an expression.
Ah right. I did wonder about tentative parsing. What about in
cp_parser_skip_to_end_of_statement?
Alternative seems to be that we explicitly handle each case.
