Ignore the include path for intrinsics coming from the toolchain. The
clang static analyzer comes with its own intrinsics and does not cope
well with intrinsics from other clang versions.
Move the relevant implementation from LibClangOptionsBuilder into the
base class so that ClangStaticAnalyzer profits from this, too.

Re-produce with:
1) Open qt-essential-includes.pro and configure it with a Qt 5.7.0 MSVC2013
64 Bit Kit.
2) Run the analyzer.
Errors during analyzing occur in winnt.h [1]. This is somehow related to
/D__int32=long that we pass on. Removing it helps.
It looks like there is no reason anymore to pass on the toolchain defines with
clang-3.8 at all. Our unit test projects can be parsed by the analyzer without
them.
Tested with the following kits:
Qt 5.6.0 (mingw39_32)
Qt 5.6.0 (msvc2013)
Qt 5.6.0 (msvc2013_64)
Qt 5.6.0 (msvc2015)
Qt 5.6.0 (msvc2015_64)
Qt 5.7.0 (mingw53_32)
Qt 5.7.0 (msvc2013)
Qt 5.7.0 (msvc2013_64)
Qt 5.7.0 (msvc2015)

libclang 3.8 seems to be sensitive to file paths separators [1]. On Windows,
this led to not updated document annotations and/or crashes after reparsing.
When passing file paths to libclang, convert to native separators.
When getting file paths from libclang, convert back.
This handles:
* main file path
* file paths of the unsaved files
* -I<DIR> arguments, the resource path (for builtins) and the paths to the
wrapped qt headers
* included header files from libclang
* source locations from libclang
Also, minimize the conversion in SourceLocation to a minimum by making
filePath() lazy.

For some reason, clang 3.8.0 on Windows does not enable exceptions anymore,
which leads to parse errors in MSVC headers (reported upstream [1]).
With this change, we can finally parse main/mainwindow.cpp of a Qt Widgets
Application for a MSVC2015 Kit and libclang 3.8.0 without any error.

This applies the following change for the clang code model, too.

Infer the version from the _MSC_FULL_VER macro, so it cannot get out of sync
with that.
Adapt the analyzer to do the same.

As for the analyzer, this makes us independent of the default triple and will
most likely reduce the maintenance - e.g. the target implies certain internal
command line arguments, we will profit from added ones.
This fixes parsing of mingw headers with the clang code model.
