c++: Fox template-introduction tentative parsing in class bodies clear
colon_corrects_to_scope_p [PR105061]
The concepts support (in particular template introductions from concepts
TS)
broke the following testcase, valid unnamed bitfields with dependent
types (or even just typedefs) were diagnosed as typos (: instead of correct
::) in template introduction during their tentative parsing.
The following patch fixes that by not doing this : to :: correction when
member_p is true.
