Patch by Matthieu Monrocq with tweaks by me to avoid StringRefs in the static
diagnostic data structures, which resulted in a huge global-var-init function.
Depends on llvm commit r132046.
llvm-svn: 132047
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.

Among other things, this makes the warning about unknown warning options mappable.
For example:
$ clang t.c -Werror -Wfoo
error: unknown warning option '-Wfoo' [-Wunknown-warning-option]
For another thing, they are properly color coded now too :)
