Add initial clang-cl support to Qt This adds the functionality to build Qt with clang under Windows against the Microsoft Visual Studio 2015 runtime. In order to replicate this, a Clang 3.8 build with Visual Studio 2015 Update 1 is needed. Adds compiler detection to Qt to distinguish correctly the clang compiler and Windows with Visual Studio. Clang has some built-in numeric functions, there is no need to use the Microsoft versions, which also conflict here.

Merge all "win32-msvc*" mkspecs into one Since we can tell the MSVC version from the compiler now, each of the qmake.conf files is now the same, so let's just have "win32-msvc" and be future-proof. Likewise for win32-clang-msvc. qplatformdefs.h was already common. Since we can't obtain the MSVC version from the unified mkspec name any more, I dropped the warning level during the qmake bootstrap to reduce the number of warnings that need to be disabled from compiler version to version. There is no point in keeping the old mkspecs, but configure will re-map the -platform argument to the unified spec as necessary, to keep existing configure command lines working. [ChangeLog][Visual Studio] Qt now has a common mkspec for all Visual Studio versions, called "win32-msvc". The old names which contained the version number are now gone (but qmake scopes based on the old names continue to work). The version of the compiler can be obtained from the MSC_VER and MSVC_VER variables (for example, for Visual Studio 2015, those contain the values 1900 and 14.0, respectively). Those variables are also available with the Intel compiler (win32-icc) and with Clang (win32-clang-msvc).

QMAKE_CFLAGS += -Wno-microsoft-enum-value
unify windows mkspecs: define c++ flags explicitly with 40e87491 merged, 'QMAKE_CXXFLAGS' variable in 'win32-g++' toolchain became defined via 'QMAKE_CFLAGS'. the similar can be found in 'win32-clang-msvc' and 'win32-icc' toolchains too. this works for now, because such definitions just duplicates code from includes, like 'gcc-base.conf', 'msvc-desktop.conf', etc. but it would became broken, if changes would be applied to 'QMAKE_CXXFLAGS' definitions in that includes, prior to the redefinitions in 'win32-*/qmake.conf' toolchains. thus 'QMAKE_CXXFLAGS' definitions in 'win32-*/qmake.conf' toolchains should not depend on 'QMAKE_CFLAGS' and be done explicitly. in order to apply this change correctly to 'win32-icc' toolchain, its 'QMAKE_CFLAGS' variable should become dependent on definitions in the includes, similar to 'win32-clang-msvc' and 'win32-msvc' toolchains.
