02eb9df851 Add new AVX512 extensions found in Intel CLX, ICL and ICX processors
Cascade Lake (CLX) added AVX512VNNI, Ice Lake has added that plus the
integer multiplication (IFMA), the vector bit manipulation instructions
(VBMI and VBMI2), bit algorithms (BITALG), the extended vector AES
instructions (VAES), among others.

I haven't turned on the configure check for those yet. I believe the
VBMI and IFMA instructions will be interesting for Qt image algorithms,
but we'll need some Ice Lakes to do benchmarking on.

In order to do that we introduce a new mkspec variable

single-$ variable references that get evaluated when loading ltcg.prf.

2e63d12183 Update supported platforms and build requirements for Apple platforms
Per earlier discussions we bump the deployment target for LTS releases
and follow up by requiring the latest SDK available for building.

As layer backed views and dark mode is a lot more stable these days in
Qt and on macOS in general we no longer support the option to build with
the 10.13 SDK. A workaround in case this functionality is still needed
is to explicitly set the QMAKE_MAC_SDK_VERSION qmake variable, which
will tell the linker to write that version into the MachO header of
the executable, which will then be read by AppKit when determining
which features to opt in to.

4d289edb14 Disable debug-and-release builds for MinGW
The requirement to separate debug and release DLLs on Windows stems from
the Visual Studio C run-time library appearing in two different variants
(debug and release) and not mixing well. It's possible to perform builds
without optimzations and with debug symbols while linking against the
release version of the C run-time, but at the same time the debug
version of the run-time brings other developer visible advantages.

MinGW on the other hand does not have this distinction, does not ship
with separate DLLS and does also not require the VS C runtime library.
Therefore we do not need this separation for MinGW, which means that our
packages can be reduced in size and application developers wishing to
debug their applications do not have to use debug builds of the Qt
libraries or run into Qt internal debug code.

1456b8091a Make it possible to undefine NDEBUG for nmake and VS projects
For nmake and VS projects we added the NDEBUG define for the release
configuration unconditionally within the qmake generators. To undefine
it, users had to use a nasty work-around.

Now, define NDEBUG within the MSVC mkspecs. In order to do that we
introduce the DEFINES_RELEASE and DEFINES_DEBUG variables that are
merged into DEFINES in default_pre.prf.

Users can unset NDEBUG by writing
    DEFINES -= NDEBUG
in their .pro file.

Note that DEFINES_RELEASE and DEFINES_DEBUG are merged in
default_pre.prf in order to give extra compilers (like moc) the chance
to see the fully resolved DEFINES variable. This is different from the
QMAKE_CFLAGS_(DEBUG|RELEASE) variables that get merged in default_post.prf.

9864d2c6f3 Revert "configure: actually resolve libraries into full filepaths"
This reverts commit 521a85395d.

Having libraries resolved to absolute file paths by configure has
annoying consequences:
1. The Qt installer needs to unabsolutify paths in all kinds of files.
This is error-prone and fragile.
2. It hurts Qt's relocatabilty. The absolute paths are unlikely to be
right on different systems.
3. Qt's configure must imitate linker behavior correctly to do the
resolution right on every platform, which is hard to get right.

Consequently, the disadvantages of 521a8539 outweigh the advantages.

7910dd0a54 Add llvm linker detection to configure
https://gcc.gnu.org/ml/gcc-patches/2018-10/msg01240.html

This is currently only used for webengine, where link time really matters.

New configure options:
* force 'lld'  '-linker lld' or' --linker=lld'
* force 'gold' '-linker gold' or '--linker=gold'
* force 'bfd' '-linker bfd' or '--linker=bfd'

Note before by default gold was always forced (if supported) now default linker
is system default one.

[ChangeLog][Tools][configure & build system] Added --linker=[bfg,lld,gold] configure flag.
