This patch allows checking whether a C++ record declaration is abstract through
libclang and clang.cindex (Python).

Alex Lorenz 690f0e2f4e [libclang] Record code-completion invocations to a temporary file when
requested by client

This is a follow up to r319702 which records parsing invocations.

These files are not emitted by default, and the client has to specify the
invocation emission path first.

Alex Lorenz 80b55ee62d [libclang] Store unsaved file hashes when recording parsing invocations
Storing the contents of unsaved files is too expensive.
Instead a hash is stored with a record invocation. When a reproducer is
generated, Clang will compare the stored hashes to the new hashes to determine
if the contents of a file has changed. This way we'll know when a reproducer was
generated for a different source to the one that triggered the original crash.

Alex Lorenz 0861579610 [libclang] Record parsing invocation to a temporary file when requested
by client

This patch extends libclang by allowing it to record parsing operations to a
temporary JSON file. The file is deleted after parsing succeeds. When a crash
happens during parsing, the file is preserved and the client will be able to use
it to generate a reproducer for the crash.

These files are not emitted by default, and the client has to specify the
invocation emission path first.

Andrew Gozillon 572bbb0754 Dependent Address Space Support
This patch relates to: https://reviews.llvm.org/D33666 This adds support
for template parameters to be passed to the address_space attribute. 
The main goal is to add further flexibility to the attribute and allow 
for it to be used easily with templates.

The main additions are a new type (DependentAddressSpaceType) alongside 
its TypeLoc and its mangling. As well as the logic required to support 
dependent address spaces which mainly resides in TreeTransform.h and 
SemaType.cpp.

Dave Lee 1a532c9e1d [index] Generate class & metaclass manglings for objc
Summary:
ObjC classes have two associated symbols, one for the class and one for the
metaclass.

This change overloads `CodegenNameGenerator::getAllManglings` to produce both
class and metaclass symbols.

While this function is called by `clang_Cursor_getCXXManglings`, it's only
called for CXXRecordDecl and CXXMethodDecl, and so libclang's behavior is
unchanged.

Faisal Vali ac506d7494 [NFC] Refactor the Preprocessor function that handles Macro definitions and rename Arguments to Parameters in Macro Definitions.
- Extracted the reading of the tokens out into a separate function.
  - Replace 'Argument' with 'Parameter' when referring to the identifiers of the macro definition (as opposed to the supplied arguments - MacroArgs - during the macro invocation).

This is in preparation for submitting patches for review to implement __VA_OPT__ which will otherwise just keep lengthening the HandleDefineDirective function and making it less comprehensible.

I will also directly update some extra clang tooling that is broken by the change from Argument to Parameter.

Hopefully the bots will stay appeased.

A suspended translation unit uses significantly less memory but on the

clang_reparseTranslationUnit to resume it or
clang_disposeTranslationUnit to dispose it completely.

This helps IDEs to reduce the memory footprint. The data that is freed
by a call to clang_suspendTranslationUnit will be re-generated on the
next (re)parse anyway. Used with a preamble, this allows pretty fast
resumption of the translation unit for further use (compared to disposal
of the translation unit and a parse from scratch).

Richard Smith e37391c4fe [modules] Round-trip -Werror flag through explicit module build.
The intent for an explicit module build is that the diagnostics produced within
the module are those that were configured when the module was built, not those
that are enabled within a user of the module. This includes diagnostics that
don't actually show up until the module is used (for instance, diagnostics
produced during template instantiation and weird cases like -Wpadded).

We serialized and restored the diagnostic state for individual warning groups,
but previously did not track the state for flags like -Werror and -Weverything,
which are implemented as separate bits rather than as part of the diagnostics
mapping information.

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).

Richard Smith 600b5261c4 PR0091R3: Implement parsing support for using templates as types.
This change adds a new type node, DeducedTemplateSpecializationType, to
represent a type template name that has been used as a type. This is modeled
around AutoType, and shares a common base class for representing a deduced
placeholder type.

We allow deduced class template types in a few more places than the standard
does: in conditions and for-range-declarators, and in new-type-ids. This is
consistent with GCC and with discussion on the core reflector. This patch
does not yet support deduced class template types being named in typename
specifiers.

Arpith Chacko Jacob fe4890a68b [OpenMP] Support for the if-clause on the combined directive 'target parallel'.
The if-clause on the combined directive potentially applies to both the
'target' and the 'parallel' regions.  Codegen'ing the if-clause on the
combined directive requires additional support because the expression in
the clause must be captured by the 'target' capture statement but not
the 'parallel' capture statement.  Note that this situation arises for
other clauses such as num_threads.

The OMPIfClause class inherits OMPClauseWithPreInit to support capturing
of expressions in the clause.  A member CaptureRegion is added to
OMPClauseWithPreInit to indicate which captured statement (in this case
'target' but not 'parallel') captures these expressions.

To ensure correct codegen of captured expressions in the presence of
combined 'target' directives, OMPParallelScope was added to 'parallel'
codegen.
