Richard Smith 1b98ccc4e9 PR20356: Fix all Sema warnings with mismatched ext_/warn_ versus 
ExtWarn/Warnings. Mostly the name of the warning was changed to match the
semantics, but in the PR20356 cases, the warning was about valid code, so the
diagnostic was changed from ExtWarn to Warning instead.

Jordan Rose 2f9cc04251 Format strings: suggest %lld instead of %qd and %Ld with -Wformat-non-iso. 
As a corollary to the previous commit, even when an extension is
available, we can still offer a fixit to the standard modifier.

Jordan Rose 92303592c3 Format strings: %Ld isn't available on Darwin or Windows. 
This seems to be a GNU libc extension; we offer a fixit to %lld on
these platforms.

Hans Wennborg aa8c61cf94 -Wformat-non-iso: warn about positional arguments (pr12017) 
This renames the -Wformat-non-standard flag to -Wformat-non-iso,
rewords the current warnings a bit (pointing out that a format string
is not supported by ISO C rather than being "non standard"),
and adds a warning about positional arguments.
