This has two main benefits:
1) introduces a qmake CONFIG we can use in .pro/.pri/.prf files
2) removes the need to keep an up-to-date list of which compilers
support the feature
The test is implemented as trying to compile every single SIMD test we
currently have, but without passing the -mXXX option. The reason for
trying all of them is that some people may have modified their mkspecs
to add -mXXX options or -march=XXX, which could enable the particular
feature we tried, resulting in a false positive outcome.

We're adding a lot of unnecessary files that end up later as cargo-cult,
for at most a handful of lines. So instead move the testcases directly
into the .json file.
The following sources were not inlined, because multiple tests share
them, and the inlining infra does not support that (yet):
- avx512
- openssl
- gnu-libiconv/sun-libiconv (there is also a command line option to
select the exact variant, which makes it hard/impossible to properly
coalesce the library sources)
The following sources were not inlined because of "complications":
- verifyspec contains a lengthy function in the project file
- stl contains lots of code in the source file
- xlocalescanprint includes a private header from the source tree via a
relative path, which we can't do, as the test's physical location is
variable.
- corewlan uses objective c++, which the inline system doesn't support
reduce_relocs and reduce_exports now create libraries with main(), which
is weird enough, but doesn't hurt.

our binary packages come without many sql drivers, because they have
proprietary dependencies we cannot ship. not every user wants to build
all of qt from scratch, so it makes sense to make it possible to
"enrich" the existing installation by compiling just the drivers. to
enable this, the drivers' configuration must be independent. but note
that it's still not possible to configure a single driver - the entire
sqldrivers directory is configured at once.
a side effect of this is that the availability of the sql plugins
cannot be made known with publicFeatures any more, because there is no
associated module pri file to put that information into. that should be
made inconsequential by making qtHaveModule() work for plugins.

This was originally enabled in the mkspecs for 64-bit QNX 7.0.0
but that broke when the qtConfig change was made. It looks like
qtConfig shouldn't be used in the platform mkspecs. I suspect
the stack-protector changes were left out of the 32-bit mkspecs
so that 6.6.0 builds wouldn't be affected.
Ignore the stack-protector/stack-protector-all possibility since
it isn't possible to access it without a command line option.
Specifying both options doesn't even make sense since
stack-protector-all encompasses stack-protector.
For now, leave out command line control of this feature.

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.

The AES instructions were first introduced with the Westmere shrink

pending on Intel architecture, but is available on AMD family 17h (gcc
argument -march=znver1).
Both features operate on SSE registers, so that's why the MSVC command-
line argument is the SSE2 one and the configure-time tests depend on
features.sse2.
The qmake feature names end in "ni" because "aes" and "sha" are too
simple and could clash with other uses. The QT_COMPILER_SUPPORTS_ macro
doesn't have the "NI" suffix because it has to match the GCC/Clang
predefined macro.
