% is a common character in IR so we'd crash on almost any malformed IR. The
diagnostic formatter expects a formatting directive when it sees an unescaped %.

This option was added in r129614 and doesn't have any use case that I'm aware
of. It's possible that external tools are using these names - and if that's
the case we can certainly reassess the functionality, but for now it lets us
shave out a few unneeded bits from clang.
Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool.
This removes the actual diagnostic name strings from clang entirely.

the command line options (at least according to GCC's documentation). GCC 4.2
didn't appear to actually do this, but it seems like that has been fixed in
later release, so we will follow the docs.

- This fixes a host of obscure bugs with regards to how warning mapping options composed with one another, and I believe makes the code substantially easier to read and reason about.

- The TextDiagnosticPrinter code is still fragile as it is just "reverse engineering" what the diagnostic engine is doing. Not my current priority to fix though.

to create it. Lit doesn't apparently clean up test directories
effectively, and so this broke randomly on subsequent runs.
Also XFAIL the test on windows, as there's not much hope for these
commands doing the right thing there.
Paired with Nick Lewycky.

- This magically enables using 'clang -cc1' as a replacement for most of 'llvm-as', 'llvm-dis', 'llc' and 'opt' functionality.
For example, 'llvm-as' is:
$ clang -cc1 -emit-llvm-bc FOO.ll -o FOO.bc
and 'llvm-dis' is:
$ clang -cc1 -emit-llvm FOO.bc -o -
and 'opt' is, e.g.:
$ clang -cc1 -emit-llvm -O3 -o FOO.opt.ll FOO.ll
and 'llc' is, e.g.:
$ clang -cc1 -S -o - FOO.ll
The nice thing about using the backend tools this way is that they are guaranteed to exactly match how the compiler generates code (for example, setting the same backend options).

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

- Currently this requires us to fake an input file.
- This allows Sema to be keep all the logic for how to pull decls out of the external AST source and how to handle things like tentative definitions.

- Doesn't actually work yet because only module level asm's get correctly marked as externally visible in the PCH.
- Other things like 'clang-cc foo.ast -ast-dump' now work, as well.
