Following up on r291465 after a regression in r276159. When we use
-fmodule-name=X while building a PCH, modular headers in X will be
textually included and the compiler knows that we are not building
module X, so don't serialize such headers in the PCH as being part of a
module, because at this point they are not.
This was causing subtle bugs and malformed AST crashes, for instance,
when using the PCH in subsequent compiler invocation with -fmodules, the
HFI for a modular header would map to the PCH, which would force a
module load of and unexistent module ID.

Summary:
In JavaScript, object literals can contain methods:
var x = {
a() { return 1; },
};
Previously, clang-format always parsed nested {} inside a braced list as
further braced lists. Special case this logic for JavaScript to try
parsing as a braced list, but fall back to parsing as a child block.

Summary:
Regex detection would incorrectly classify a trailing `!` operator
(nullability cast) followed by a `/` as the start of a regular
expression literal. This fixes code such as:
var foo = x()! / 10;
Which would previously parse a regexp all the way to the end of the
source file (or next `/`).

Summary:
In JavaScript, classes are expressions, so they can appear e.g. in
argument lists.
var C = foo(class {
bar() {
return 1;
}
};

We model deduction-guides as functions with a new kind of name that identifies
the template whose deduction they guide; the bulk of this patch is adding the
new name kind. This gives us a clean way to attach an extensible list of guides
to a class template in a way that doesn't require any special handling in AST
files etc (and we're going to need these functions we come to performing
deduction).

GCC 7 will predefine two new macros on s390x:
- __ARCH__ indicates the ISA architecture level
- __VX__ indicates that the vector facility is available
This adds those macros to clang as well to ensure continued
compatibility with GCC.

It also adds code to define the correct preprocessor macros for each

Summary:
Previously the method would simply return false, causing every single
inline assembly constraint to trigger a compile error.
This adds inline assembly constraint support for the AVR target.
This patch is derived from the code in
AVRISelLowering::getConstraintType.

GCC does not generate `__unix` nor `unix` macros. The latter already
intrudes into the user's namespace and should be avoided. Use the

While there is nothing to do at link time to get pthreads support on

After r260016 and r260017 disabled typo correction for ivars and properties
clang didn't report errors about unresolved identifier in the base of ivar and
property ref expressions. This meant that clang invoked CodeGen on invalid AST
which then caused a crash.
This commit re-enables typo correction for ivars and properites, and fixes the
PR25113 & PR26486 (that were originally fixed in r260017 and r260016) in a
different manner by transforming the Objective-C ivar reference expression with
'IsFreeIvar' preserved.

Summary:
The patch updates the MSVC ToolChain for the changes made in Visual
Studio 2017[1].
Other notable changes:
- Path handling code has been centralised to make potential future
changes less painful.
- A compiler error is emitted if the driver is unable to locate a
usable MSVC toolchain. (Previously it'd fail with a cryptic error
such as "link.exe is not executable")
- Support for the new Setup Config Server API[2] has been added,
albeit block commented out with a preprocessor conditional. This can
probably be re-evaluated when the API is officially released (it's
currently at the RC stage), but it's left in to make it easy for
anyone familiar with the API to give it a go with Clang.

Summary:
The breaking of line comment sections was misaligning the case where the first comment line is on an unwrapped line containing newlines. In this case, the breaking column must be based on the source column of the last token that is preceded by a newline, not on the first token of the unwrapped line.

```
enum A {
a, // line 1
