Introduce a limit on the depth of the template instantiation backtrace
we will print with each error that occurs during template
instantiation. When the backtrace is longer than that, we will print
N/2 of the innermost backtrace entries and N/2 of the outermost
backtrace entries, then skip the middle entries with a note such as:
note: suppressed 2 template instantiation contexts; use
-ftemplate-backtrace-limit=N to change the number of template
instantiation entries shown
This should eliminate some excessively long backtraces that aren't
providing any value.
