Creating a precompiled header exclusively for a one- or two-file module
is wasteful. The time that it takes to build the precompiled source is
on the same order as a regular compilation, so enabling precompiled
headers for those modules just makes the build slower.
Also make it possible to override the precompiled header by just setting
PRECOMPILED_HEADER to empty.

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.

The configure-time detection (cxx11default) isn't enough if the compiler
can be changed. This is especially necessary if Qt is compiled with a
compiler that defaults to >= C++11 (e.g., GCC 6) and then the user
selects a compiler another compiler (e.g., Clang) via -spec option. In
that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the
command-line, causing the compilation to fail.
As a nice side-effect, even moc without moc_predefs.h will now get the
__cplusplus setting.

Sometimes, users need to add compiler flags to QMAKE_CXXFLAGS that
aren't supposed to be passed to the predefs dump. That's especially true
for -include options, as that would change completely what's
defined. Not to mention that -include is a preprocessor option and
shouldn't be in CXXFLAGS in the first place (Automake has CPPFLAGS, but
qmake only has INCLUDEPATH and DEFINES).
