This formatting library will be used by a stand-alone clang-format tool
and can also be used when writing other refactorings.

Manuel's original design document:
https://docs.google.com/a/google.com/document/d/1gpckL2U_6QuU9YW2L1ABsc4Fcogn5UngKk7fE5dDOoA/edit

The library can already successfully format itself.

Recursively prune some includes.

Pull the Attr iteration parts out of Attr.h, so including DeclBase.h doesn't pull in all the generated Attr code.

Required to pull some functions out of line, but this shouldn't have a perf impact.

diagnostic range printing print nicer results for token pastes.

Don't emit a warning with an input/output parameter. We assume the user knows what they're doing here.

state so that all of the various clones end up rendering their
diagnostics into the same serialized-diagnostics file. This is
important when we actually want failures during module build to be
reported back to the translation unit that tried to import the
not-yet-built or out-of-date module. <rdar://problem/12565727>

an include stack, e.g.,

import of that module elsewhere, don't try to build the module again:
it won't work, and the experience is quite dreadful. We track this
information somewhat globally, shared among all of the related
CompilerInvocations used to build modules on-the-fly, so that a
particular Clang instance will only try to build a given module once.

1) init-order sanitizer: initialization-order checker.
Status: usable, but may produce false positives w/o proper blacklisting.
2) use-after-return sanitizer
Status: implemented, but heavily understed.
Should be optional, as it significanlty slows program down.
3) use-after-scope sanitizer
Status: in progress.

Original commit message:

Remove redundant code.

llvm-svn: 168900

Among other differences, GCC accepts

  typedef int IA[];
  typedef int A10[10];
  static A10 *f(void);
  static IA  *f(void);
  void g(void) {
    (void)sizeof(*f());
  }

but clang used to reject it with:

  invalid application of 'sizeof' to an incomplete type 'IA' (aka 'int []')

The intention of c99's 6.2.7 seems to be that we should use the composite type
and accept as gcc does.

Doing the type merging required some extra fixes:
  * Use the type from the function type in initializations, even if an parameter
    is available.
  * Fix the merging of the noreturn attribute in function types.
  * Make CodeGen  handle the fact that an parameter type can be different from
    the corresponding type in the function type.
