constify struct block in some places
This makes some spots in gdb, particularly general_symbol_info, use a "const struct block", then fixes the fallout. The justification is that, ordinarily, blocks ought to be readonly. Note though that we can't add "const" in the blockvector due to block relocation. This can be done once blocks are made independent of the program space. 2014-06-18 Tom Tromey <tromey@redhat.com> * varobj.c (varobj_create): Update. * valops.c (value_of_this): Update. * tracepoint.c (add_local_symbols, scope_info): Update. * symtab.h (struct general_symbol_info) <block>: Now const. * symtab.c (skip_prologue_sal) (default_make_symbol_completion_list_break_on) (skip_prologue_using_sal): Update. * stack.h (iterate_over_block_locals) (iterate_over_block_local_vars): Update. * stack.c (print_frame_args): Update.
