ClangStaticAnalyzer: Stop passing on toolchain defines for qmake/msvc case

Browse Source 
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)
	Qt 5.7.0 (msvc2015_64)
