Move struct buildsym_compunit to buildsym.h
This moves struct buildsym_compunit to buildsym.h. Now that the members are private, and it no longer affects any global state in buildsym.c, an instance can be used directly for symtab creation. gdb/ChangeLog 2018-07-20 Tom Tromey <tom@tromey.com> * buildsym.h (struct buildsym_compunit): Move from buildsym.c. * buildsym.c (struct buildsym_compunit): Move to buildsym.h. (buildsym_compunit::buildsym_compunit) (buildsym_compunit::~buildsym_compunit) (buildsym_compunit::get_macro_table): Define.
