Patch by Anders Carlsson with minor refactoring by me.

We've decided to make the core rewriter class and PP rewriters mandatory.
They're only a few hundred lines of code in total and not worth supporting as a
distinct build configuration, especially since doing so disables key compiler
features.
This reverts commit r213150.
Revert "clang/test: Introduce the feature "rewriter" for --enable-clang-rewriter."
This reverts commit r213148.
Revert "Move clang/test/Frontend/rewrite-*.c to clang/test/Frontend/Rewriter/"
This reverts commit r213146.

Otherwise, multiple errors such as having unknown identifiers for two
arguments won't be diagnosed properly (e.g. only the first one would
have a diagnostic message if typo correction fails even though both
would be diagnosed if typo correction suggests a replacement).

than one method with mismatched type of same selector name.
clang issues a warning to point this out since it may cause
undefined behavior. There are cases though that some APIs
don't care about user methods and such warnings are perceived as
noise. This patch allows users to add paren delimiters around
selector name to turn off such warnings. So, @selector((save:)) will
turn off the warning. It also provides 'fixit' so user knows
what to do. // rdar://16458579

to call themselves will get the warning:
"Capturing <itself> strongly in this block is likely to
lead to a retain cycle". Cut down on the amount of noise
by noticing that user at some point sets the captured variable
to null in order to release it (and break the cycle).

The thread safety analysis isn't very useful in ObjC (you can't annotate
ObjC classes or methods) but we can still analyze the actual code and
show violations in usage of C/C++ functions.
Fixes PR19541, which does not use thread safety attributes but crashes
with -Weverything.

This tests for broad compatibility with platform SDK headers using the clang
driver and so belongs alongside the other header ingtegration tests.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

-Wselector-type-mismatch default again. After
internal discussions, we think that in most cases
it has helped our developers find hard to detect
undefined behaviors. We are going to provide a syntax
(and fix-it) to suppress the warning in remaining of
false positive cases.
