- This ended up being hard to factor, sorry for the large diff.

 - Some post-commit cleanup to come.

Move tools/wpa to examples/wpa, and unbreak its build.

 - Expects the plugin has been loaded with -load.

 - Using this may require disabling TOOL_NO_EXPORTS in the clang-cc Makefile, this breaks the llvm::Registry way of working (static constructors are bad, kids). This should be replaced with a "real" plugin model that has explicit plugin interfaces.

 - We still need support for detecting the target features, since the name
   doesn't actually do a good job of decribing what the CPU supports (for LLVM).

Add an internal CreateRecordDecl that will create a CXXRecordDecl when compiling C++ and a RecordDecl otherwise.

- Have TryStaticImplicitCast set the cast kind to NoOp when binding a reference. CheckReferenceInit already inserts implicit casts to the necessary types. This fixes an assertion in CodeGen for some casts and brings a fix for PR5453 close, if I understand that bug correctly.
- Also, perform calculated implicit cast sequences if they're determined to work. This finally diagnoses static_cast to ambiguous or implicit bases and fixes two long-standing fixmes in the test case. For the C-style cast, this requires propagating the access check suppression pretty deep into other functions.
- Pass the expressions for TryStaticCast and TryStaticImplicitCast by reference. This should lead to a better AST being emitted for such casts, and also fixes a memory leak, because CheckReferenceInit and PerformImplicitConversion wrap the node passed to them. These wrappers were previously lost.

  StringRef.data() which doesn't guarantee null-termination.

Please report any discrepancies you see in clang-cc, I'm not confident that our regression tests cover all the fun ways one can use clang-cc.

 - This reimplements -verify as just another DiagnosticClient, which buffers the diagnostics and checks them when the source file is complete. There are some hacks to make this work, but they are all internal, and this exposes a better external interface.

 - This also tweaks a few things:
   o Errors are now just regular diagnostics.
   o Frontend diagnostics are now caught (for example, errors in command line arguments), although there isn't yet a way to specify that they are expected. That would be nice though.

 - Not yet used.
