Neither the Intel compiler nor Visual C++ have a dedicated switch to
enable F16C support, like GCC and Clang do. So we used the AVX switch
for that in commit 8241d51f70, as it was
the closest, lowest denominator. That was incorrect and insufficient.
The Intel compiler silently miscompiles the intrinsics with -xAVX,
making calls to out-of-line functions like _mm_cvtps_ph, which don't
exist. So we actually have to use AVX2 support to generate correct code.
That might be a problem later, since Ivy Bridge supports F16C but not
AVX2.
Visual C++ is able to generate F16C code with just -arch:AVX.
Either way, since there's no dedicated command-line switch, there's also
no dedicated preprocessor macro. We're using __AVX2__ for both
compilers, as that's a sufficient condition to indicate a processor that
supports F16C.

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).

This is needed in order to be able to specify a custom location of
the ANGLE libs, and enables us to perform a LoadLibrary of ANGLE libs
by just having the absolute path to QtANGLE.dll as the argument to
LoadLibrary().
Previously, we had two ANGLE libraries: libEGL and libGLESv2. libEGL hard
linked against libGLESv2. If we wanted to load libEGL from a custom
location, we couldn't load libEGL by calling LoadLibrary with the absolute
path to libEGL, because libEGL had problems finding libGLESv2. One
solution to that could have been to call SetDllDirectory() with the path
to the ANGLE libs before calling LoadLibrary("libEGL.dll"). Since the DLL
directory would point to both ANGLE libs, this would ensure that the libGLESv2
was also found. Unfortunately, this approach is not thread safe
(SetDllDirectory will affect all subsequent LoadLibrary(Ex) from the same
process). Therefore, we chose to merge the two libraries into one to
circumvent the whole problem.
At the same time, this patch also enables loading of two different ANGLE
libraries into the same process at once without renaming them: This was
not possible before because libEGL hard linked to libGLESv2.dll. When
libGLESv2.dll was already loaded, the second instance of libEGL would
simply link against the already loaded version of libGLESv2.dll.
This behavior is documented in the LoadLibraryEx documentation on MSDN:
"If the string specifies a module name without a path and more than one
loaded module has the same base name and extension, the function returns a
handle to the module that was loaded first."

The patch introduces a new build configuration on Windows which
can be requested by passing -opengl dynamic to configure.
Platforms other than Windows (including WinRT) are not affected.
The existing Angle and desktop configurations are not affected.
These continue to function as before and Angle remains the default.
In the future, when all modules have added support for the dynamic
path, as described below, the default configuration could be changed
to be the dynamic one. This would allow providing a single set of
binaries in the official builds instead of the current two.
When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are
never defined. Instead, the code path that has traditionally been
desktop GL only becomes the dynamic path that has to do runtime
checks. Qt modules and applications are not linked to opengl32.dll or
libegl/glesv2.dll in this case. Instead, QtGui exports all necessary
egl/egl/gl functions which will, under the hood, forward all requests
to a dynamically loaded EGL/WGL/GL implementation.
Porting guide (better said, changes needed to prepare your code to
work with dynamic GL builds when the fallback to Angle is utilized):
1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to
differentiate between desktop and ES where needed. Keep in mind that
it is the desktop GL header (plus qopenglext.h) that is included,
not the GLES one.
QtGui's proxy will handle some differences, for example calling
glClearDepth will route to glClearDepthf when needed. The built-in
eglGetProcAddress is able to retrieve pointers for standard GLES2
functions too so code resolving OpenGL 2 functions will function
in any case.
2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds,
but never "angle" or "opengles2".
3. The preprocessor define QT_OPENGL_DYNAMIC is also available in
dynamic builds. The usage of this is strongly discouraged and should
not be needed anywhere except for QtGui and the platform plugin.
4. Code in need of the library handle can use
QOpenGLFunctions::platformGLHandle().
The decision on which library to load is currently based on a simple
test that creates a dummy window/context and tries to resolve an
OpenGL 2 function. If this fails, it goes for Angle. This seems to work
well on Win7 PCs for example that do not have proper graphics drivers
providing OpenGL installed but are D3D9 capable using the default drivers.
Setting QT_OPENGL to desktop or angle skips the test and forces
usage of the given GL. There are also two new application attributes
that could be used for the same purpose.
If Angle is requested but the libraries are not present, desktop is
tried. If desktop is requested, or if angle is requested but nothing
works, the EGL/WGL functions will still be callable but will return 0.
This conveniently means that eglInitialize() and such will report a failure.
Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will
tell which implementation is chosen.
The textures example application is ported to OpenGL 2, the GL 1
code path is removed.
[ChangeLog][QtGui] Qt builds on Windows can now be configured for
dynamic loading of the OpenGL implementation. This can be requested
by passing -opengl dynamic to configure. In this mode no modules will
link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will
dynamically choose between desktop and Angle during the first GL/EGL/WGL
call. This allows deploying applications with a single set of Qt libraries
with the ability of transparently falling back to Angle in case the
opengl32.dll is not suitable, due to missing graphics drivers for example.
