Darwin-embedded: find correct libclang_rt for embedded targets.
This refactors some of the Darwin toolchain classification to give a more solid
distinction between the three primary Darwin platforms (OS X, IOS and IOS
simulator) so that a 4th choice can be added temporarily: embedded MachO
targets.
Longer term, this support will be factored out into a separate class and no
longer classified as "darwin-eabi", but the refactoring should still be useful.

Change semantics of regex expectations in the diagnostic verifier
Previously, a line like
// expected-error-re {{foo}}
treats the entirety of foo as a regex. This is inconvenient when matching type
names containing regex characters. For example, to match
"void *(class test8::A::*)(void)" inside such a regex, one would have to type
"void \*\(class test8::A::\*\)\(void\)".
This patch changes the semantics of expected-error-re to only treat the parts
of the directive wrapped in double curly braces as regexes. This avoids the
escaping problem and leads to nicer patterns for those cases; see e.g. the
change to test/Sema/format-strings-scanf.c.
(The balanced search for closing }} of a directive also makes us handle the
full directive in test\SemaCXX\constexpr-printing.cpp:41 and :53.)

[objcmt] When emitting a remap file, use a json format with the edit entries, instead of applying the changes
to a temp file directly.
This allows to combine the edits when they can be different based on whether you saw
the implementation or not, e.g. with the designated initializer migration.
[objcmt] When whitelisting the headers we want to modify, allow changing the
the ObjC implementation declarations, just don't change implementations for
classes that are not in the whitelisted headers.
For example, if we change a method to return 'instancetype' we should also
update the method definition in the implementation.

Better diagnostic for static override when methods are thiscall by default
Methods are thiscall by default in the MS ABI, and also in MinGW targetting GCC 4.7 or later.
This changes the diagnostic from the technically correct but hard to understand:
virtual function 'foo' has different calling convention attributes ('void ()') than the function it overrides (which has calling convention 'void () __attribute__((thiscall))')
to the more intuitive and also correct:
'static' member function 'foo' overrides a virtual function
We already have a test for this. Let's just run it in both ABI modes.

That's a mouthful, and not necessarily the final name. This also

that a protocol, when adopted by a class, is explicitly implemented

Support GNU style rule to put a space before opening parenthesis.
Summary:
The rule from the GNU style states:
"We find it easier to read a program when it has spaces before the open-parentheses and after the commas."
This patch makes clang-format adds an option to put spaces before almost all open parentheses, except the cases, where different behavior is dictated by the style rules or language syntax:
* preprocessor:
** function-like macro definitions can't have a space between the macro name and the parenthesis;
** `#if defined(...)` can have a space, but it seems, that it's more frequently used without a space in GCC, for example;
* never add spaces after unary operators;
* adding spaces between two opening parentheses is controlled with the `SpacesInParentheses` option;
* never add spaces between `[` and `(` (there's no option yet).
