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.

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.

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.

This is useful for parsing a single file, as a fast/inaccurate 'mode' that can still provide declarations from the file, like the classes and their methods.

A suspended translation unit uses significantly less memory but on the
other side does not support any other calls than
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).

This allows users to query the target triple and target pointer width, which
would make me able to fix https://github.com/servo/rust-bindgen/issues/593 and
other related bugs in an elegant way (without having to manually parse the
target triple in the command line arguments).

In such a case, as when using the NS_ENUM macro, for indexing purposes treat the typedef as 'transparent',
meaning we treat its references as symbols of the underlying tag symbol.
Also provide a libclang API to check for such typedefs.

clang_CXXConstructor_isDefaultConstructor,
clang_CXXConstructor_isMoveConstructor,
clang_CXXMethod_isDefaulted
I need (some of) these methods for a C++ code model I am building in Python to drive a code generator.

This behavior is enabled when the new CXTranslationUnit_KeepGoing
option is passed to clang_parseTranslationUnit{,2}. It is geared
towards use by IDEs and similar consumers of the clang-c API where
fatal errors may arise when parsing incomplete code mid-edit, or
when include paths are not properly configured yet. In such situations
one still wants to get as much information as possible about a TU.
Previously, the semantic analysis would not instantiate templates
or report additional fatal errors after the first fatal error was
encountered.
Fixes PR24268.

When reparsing a translation unit with preamble generation turned on,
no includes are found. This is due to the fact that all SLocs from
AST/PCH files are skipped as they are 'loaded', and inclusions from a
preamble are also 'loaded'. So, in case a file has a preamble, it first
needs to process those loaded inclusions, and then check for any local
inclusions. This latter one is for any includes that are not part of the
preamble, like includes half-way through a file.
This fixes PR24748.

Summary:
The current default is to create the preamble on the first reparse, aka
second parse. This is useful for clients that do not want to block when
opening a file because serializing the preamble takes a bit of time.
However, this makes the reparse much more expensive and that may be on the
critical path as it's the first interaction a user has with the source code.
YouCompleteMe currently optimizes for the first code interaction by parsing
the file twice when loaded. That's just unnecessarily slow and this flag
helps to avoid that.

Right now clang_Cursor_getMangling will attempt to mangle any
declaration, even if the declaration isn't mangled (extern C). This
results in a partially mangled name which isn't useful for much. This
patch makes clang_Cursor_getMangling return an empty string if the
declaration isn't mangled.

This function permits the mangling of a C++ 'structor. Depending on the ABI and
the declaration, the declaration may contain more than one associated symbol for
a given declaration. This allows the consumer to retrieve all of the associated
symbols for the declaration the cursor points to.

When we only have a buffer from one of the two reparse calls, we can
just return that buffer rather than going through the realloc/memcpy

I'm not sure now how this should be fixed. %lld is non-standard
and not accepted by mingw on Windows while PRId64 is bad for this bot.
Is long long longer than 64 bits here? if not, why is PRId64
incompatible with it? something seems wrong.
Probably all the datatypes should be replaced to unsigned or uint64_t
depending upin requirements instead of the non standard long long.
