Craig Topper 32c959dab3 [X86] Remove 'umip' feature flag.
This feature flag indicates that the processor has support for removing certain instructions from user mode software. But the feature flag by itself doesn't indicate if the support is enabled in the OS. The affected instructions aren't even instructions the compiler would emit. So I don't think think this feature flag should be in the compiler.

Bruno Cardoso Lopes 17da34d2bd [PCH] Fix a regression when PCH is used with -fmodules
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.

Martin Probst 8e3eba0373 clang-format: [JS] correcly format object literal methods.
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.

Martin Probst 16282993b7 clang-format: [JS] exclaim preceding regex literals.
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 `/`).

Richard Smith 3584515018 P0091R3: Implement basic parsing support for C++17 deduction-guides.
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).

Alex Lorenz 776b417634 [Sema][ObjC++] Typo correction should handle ivars and properties
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.

Reid Kleckner 723fabfcdf [Driver] Updated for Visual Studio 2017
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.

Patch by Hamza Sood.
