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.

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 `/`).

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).

- __VX__ indicates that the vector facility is available
