Flip the default for showing include stacks on notes to false. This
required modifying a few tests that specifically use note include stacks
to check the source manager's view of include stacks. I've simply added
the flag to these tests for now, they may have to be more substantially
changed if we decide to remove support for note include stacks
altogether.

Also, add a test for include stacks on notes that was supposed to go in
with the previous commit.

Add an option to suppress include stack printing on note diagnostics.
These stacks are often less important than those on primary diagnostics.

As the number of notes grows, this becomes increasingly important. The
include stack printing is clever and doesn't print stacks for adjacent
diagnostics from the same file, but when a note is in between a sequence
of errors in a header file, and the notes all refer to some other file,
we end up getting a worst-case ping-pong of include stacks that take up
a great deal of vertical space.

Still, for now, the default behavior isn't changed. We can evaluate user
feedback with the flag.

Patch by Richard Trieu, a couple of style tweaks from me.

Remove the AST printer (-ast-print-xml), which is too incomplete and
too low-level to actually be useful but is just interesting enough for
people to try to use it (which won't actually work beyond toy examples).

To bring back the AST printer, it needs to be:
- Complete, covering all of C/C++/Objective-C
- Documented, with appropriate Schema against which we can validate
the output
- Designed for C/C++/Objective-C, not Clang's specific ASTs
- Stable across Clang versions
- Well-tested
