The grammar has:
mem-initializer-id:
class-or-decltype
identifier
class-or-decltype:
nested-name-specifier[opt] type-name
nested-name-specifier template simple-template-id
computed-type-specifier
computed-type-specifier:
decltype-specifier
pack-index-specifier
splice-type-specifier
but we weren't parsing splice-type-specifier in there, just in
cp_parser_base_specifier. So, the following patch defers
similarly to cp_parser_base_specifier the typename diagnostics
because we don't know whether typename [: will be valid or not
- it could be splice-scope-specifier and in that case typename
is not valid, or splice-type-specifier, in which case it is valid
but not required. And calls cp_parser_splice_type_specifier too
when nested-name-specifier nor :: don't appear.
