Some distributions do not define MINGW_HAS_SECURE_API globally,
resulting in methods like wgetenv_s not being declared in the
headers.
This is probably to keep compatibility with Windows XP. Anyhow,
we don't support Windows XP anymore, so we can safely add the
define.
Note that this is not necessary for the mingw-builds distro,
which is the only one we test and support. Anyhow, I don't
see any risk in adding these for other distributions.

As the comment says, Haswell is a nice divider and is a good
optimization target.
I'm using -march=core-avx2 instead of -march=haswell because the latter
form was only added to GCC 4.9 but we still support 4.7 and that has
support for AVX2.
This commit changes the AVX2-optimized code in QtGui to Haswell-
optimized instead. That means, for example, that qdrawhelper_avx2.cpp
can now use the FMA instructions.

This allows distinguishing between these tools and tools for the host,
when cross compiling.
While mac tools normally only are available on macOS, there are third
party efforts to port them to other platforms. In these cases, it
might be useful to use a prefix (either some sort of triplet prefix,
or an absolute path) to distinguish between the host build platform
compilers/tools and the ones for the cross target.
The use of this variable matches the one used in a lot of other
mkspecs, and shouldn't cause any issues for those who aren't setting
it.

Add support for QSurface::VulkanSurface and QVulkanWindow.
Usage:
1) Build MoltenVK according to instructions
2) Configure Qt: ./configure -I /path/to/MoltenVK/Package/Release/MoltenVK/include
3) export QT_VULKAN_LIB=/path/to/MoltenVK/Package/Release/MoltenVK/macOS/libMoltenVK.
Implement support for QSurface::VulkanSurface by enabling
layer mode for QNSView and then creating a CAMetalLayer,
which the MoltenVK translation layer can run on.
MoltenVK provides an implementation of the Vulcan API,
which means that the platform integration is similar
to other platforms: implement a QCocoaVulkanInstance
where we pass the QNSView instance to the vkCreateMacOSSurfaceMVK
Vulkan surface constructor function.
Using Vulkan directly without QVulkanWindow is possible, but not
tested.
We currently load libMoltenVK at run-time and use the
existing QT_VULKAN_LIB environment variable to set its
path. For deployment purposes it would be better to
link against MoltenVK.frameworkm, but this

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.

Building qt with msvc would fail with the -developer-build configure
option turned on under simplified chinese locale.
This is because msvc will emit warnings for source files with utf-8
characters which are not representable in CP936, and -developer-build
implies treating warnings as errors.
This patch turn on -utf-8 compiler option for msvc2015 update 2
and up only for building qt.

The uvfd flag is implicitly defined when -Olink is used.
This causes the compiler to generate a warning for every
file being compiled in release mode.

Is a privateConfig to limit it to the default Qt build.

newer version which does not rely on that define, first included in 5.5.

this is mostly for appearances (as evidenced by everything working
despite it being missing from some specs), as the variable is just a
fallback for moc.prf's automatic detection.

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).

We're asking the compiler anyway, so we can fully use this information
just as well. Note that this actually happens after the spec itself has
been processed, so it was necessary to delay the version-specific flag
handling as well.

this makes it consistent with the determination of the default
include/library paths. this makes sense, as it's possible to switch the
sdk/toolchain after building qt (within reason).
a side effect of this change is that for compilers which emulate other
compilers, both the real and the emulated version are now made
available.
