[PATCH 9/9] gdb: fix some comments in global_symbol_searcher

[Simon Marchi <simon.marchi@efficios.com>]

Fix a few comments in and around global_symbol_searcher:

 - The comment of global_symbol_searcher::m_exclude_minsyms refers to
   M_SYMBOL_REGEXP, which does not (or no longer) exist.  It means
   M_SYMBOL_NAME_REGEXP.

 - The comment in global_symbol_searcher::add_matching_msymbols refers
   to find_pc_symtab, which does not exist anymore.  The code calls
   find_compunit_symtab_for_pc.

 - The comment of global_symbol_searcher calls it a structure, but it
   is a class.
