[libclang] Fix LibclangReparseTest.FileName when TMPDIR is set to a symlink

Fix testing of clang_File_tryGetRealPathName() in
LibclangReparseTest.FileName when executing in an environment which has
TMPDIR set to a symbolic link that points to an actual directory. The
test would fail because the name returned by
clang_File_tryGetRealPathName() has the symlink resolved but the test
compared it to the original filename of a temporary file.

The patch addresses the problem by checking only that the value returned
by clang_File_tryGetRealPathName() ends with "main.cpp".

Additionally, the patch makes the previous assertion in the test that
checks result of clang_getFileName() stricter. It newly verifies that
the name returned by the function is exactly same as what was given to
clang_parseTranslationUnit()/clang_getFile().

Defer adding keywords to the identifier table until after the language options have been loaded from the AST file.

This fixes issues with "class" being reported as an identifier in "enum class" because the construct is not present when using default language options.

[libclang] Add clang_File_tryGetRealPathName

Summary:
clang_getFileName() may return a path relative to WorkingDir.
On Arch Linux, during clang_indexTranslationUnit(), clang_getFileName() on
CXIdxIncludedIncludedFileInfo::file may return
"/../lib64/gcc/x86_64-pc-linux-gnu/7.3.0/../../../../include/c++/7.3.0/string",
for `#include <string>`.

I presume WorkingDir is somehow changed to /usr/lib or /usr/include and
clang_getFileName() returns a path relative to WorkingDir.

clang_File_tryGetRealPathName() returns "/usr/include/c++/7.3.0/string"
which is more useful for the indexer in this case.

[libclang] Add PrintingPolicy for pretty printing declarations

Summary:
Introduce clang_getCursorPrettyPrinted() for pretty printing
declarations. Expose also PrintingPolicy, so the user gets more
fine-grained control of the entities being printed.

The already existing clang_getCursorDisplayName() is pretty limited -
for example, it does not handle return types, parameter names or default
arguments for function declarations. Addressing these issues in
clang_getCursorDisplayName() would mean to duplicate existing code
(e.g. clang::DeclPrinter), so rather expose new API to access the
existing functionality.

The gcc documentation says “On GNU/Linux, <stdc-predef.h> is pre-included.” See https://gcc.gnu.org/gcc-4.8/porting_to.html;

The preinclude is inhibited with –ffreestanding.

Basically I fixed the failing test cases by adding –ffreestanding which inhibits this behavior.

I fixed all the failing tests, including some in extra/test, there's a separate patch for that which is linked here

Note: this is a recommit after a test failure took down the original (r318669)

[libclang] Add clang_getAllSkippedRanges function

This complements the clang_getSkippedRanges function which returns skipped ranges filtered by a specific file.

This function is useful when all the ranges are desired (and a lot more efficient than the equivalent of asking for the ranges file by file, since the implementation of clang_getSkippedRanges iterates over all ranges anyway).

This provides both a more uniform interface and makes libclang behave like
clang tooling wrt relative paths against argv[0]. This is necessary for
finding paths to a c++ standard library relative to a clang binary given
in a compilation database. It can also be used to find paths relative to
libclang.so if the full path to it is passed in.

Add clang_free to libclang to free memory allocated in libclang.

One of the problems libclang tests has running under Windows is memory
allocated in libclang.dll but being freed in the test executable, possibly
by a different memory manager. This patch exposes a new export function,
clang_free(), used to free any allocated memory with the same libclang.dll
memory manager that allocated the memory.
