Change `minimal_symbols' to std::vector in linespec.c structures
This patch converts linespec.c's linespec.label_symbols member from a VEC to a std::vector. gdb/ChangeLog: * linespec.c (struct linespec) <minimal_symbols>: Change type to std::vector. Update all users. (convert_linespec_to_sals): Use std::sort to sort minimal symbols. (struct collect_info) <minimal_symbols>: Likewise. (compare_msymbols): Return bool. Change parameters to const bound_minimal_symbol references. (find_method, find_function_symbols, find_linespec_symbols): Change `minsyms' parameter to std::vector. Update all callers.
