[PATH] Patch to fix -finstrument-functions-exclude-function-list handling of namespaces and escaped commas

[Oliver Browne]

Patch fixes following PRs:
c++/90816 - -finstrument-functions-exclude-function-list improperly
handles namespace/class definitions
c++/90809 - -finstrument-functions-exclude-function-list mishandles
comma escaping

Fixes as follows:
At flag_instrument_functions_exclude_p [gimplify.c]
Using lang_hooks.decl_printable_name (fndecl, 1) to get namespace /
class information as part of printable name to allow for
inclusion of namespace / class specification when passing symbols to
-finstrument-functions-exclude-function-list. Was
previously lang_hooks.decl_printable_name (fndecl, 0).

At add_comma_separated_to_vector [opts.c]
Added writing of a null character to w after primary loop finishes, to
account for offset between r and w when r reaches end of
passed string.
