The linker must not throw away the lto.o file. We now instruct the
linker to create a non-temporary lto.o, dependent on the target name.
In order to do that we introduce a new mkspec variable
QMAKE_LFLAGS_LTCG_SEPARATE_DEBUG_INFO. This variable can contain
single-$ variable references that get evaluated when loading ltcg.prf.

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.

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.

For nmake and VS projects we added the NDEBUG define for the release

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.

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.

When QFile::open is called with the NewOnly flag, the call will
fail if the file already exists. As usual, if the file does not exist,
it will be created. Like QTemporaryFile, there is a guarantee from
the operating system that you are not accidentally creating a new file
on top of an older file. When QFile::open is called with the
ExistingOnly flag, the call will fail if the file does not exist. The
ExistingOnly flag only provides new functionality when used with the
WriteOnly flag. For ReadOnly it provides no change in functionality,
as ReadOnly by itself already never creates.

mingw-w64 toolchain:
- add missing compiler definitions, similar to
'msvc-desktop.conf' toolchain,
- describe the reasons of missing compiler definitions, available in
'msvc-desktop.conf' toolchain,
- add missing 'QMAKE_CXXFLAGS' and 'QMAKE_CXXFLAGS_WARN_ON' variables,
similar to 'msvc-desktop.conf' toolchain.
ICC on Windows toolchain:
- add 'QMAKE_CFLAGS_OPTIMIZE_FULL' variable, similar to 'gcc-base.conf'
toolchain, though left it unused for now,
- add missing flags to 'QMAKE_CFLAGS' variable, similar to
'msvc-desktop.conf' toolchain,
- update deprecated 'Qwd' flag with 'Qdiag-disable',
- use 'QMAKE_CFLAGS_OPTIMIZE_DEBUG' variable instead of '-Od' flag,
similar to 'gcc-base.conf' toolchain (ICC implies '-O2' optimization
level by default, while MSVC implies '-Od'),
- add 'QMAKE_CFLAGS_UTF8_SOURCE' variable, similar to
'msvc-version.conf' toolchain; use a workaround to initialize it,
until '-utf-8' flag would be supported by ICC on Windows,
- update deprecated '-Qstd=c++1z' flag with '-Qstd=c++17',
MSVC toolchain:
- remove 'incremental' from MSVC 'CONFIG' variable, since it has
relevance only for the Unix generator,
- add 'QMAKE_CFLAGS_OPTIMIZE_DEBUG' variable, used in ICC for Windows
toolchain,
- add empty 'QMAKE_LIBS' variable, similar to 'win32-g++' toolchain,
- add 'uuid.lib' library to 'QMAKE_LIBS_GUI' variable, similar to
'win32-g++' toolchain,
- add C++14 and C++17 language support flags, though left them disabled
for now, similar to 'win32-icc' toolchain.

Common changes to mingw-w64, ICC on Windows, and MSVC toolchains:
- set similar order of variables and its splitting into sections,
- set similar order of flags in variables and the way they are set.
mingw-w64 toolchain:
- move 'gcc-base.conf' include before setting Windows specific
flags, similar to include 'msvc-desktop.conf' in ICC on Windows
toolchain; this leads to consistency with other toolchains
and allows to safely override common GCC variables with Windows
specific ones, when needed,
- move 'QMAKE_EXT_OBJ' and 'QMAKE_EXT_RES' variables to the linker
flags section, according to its purpose.
MSVC toolchain:
- set flags order in 'CONFIG' variable, similar to mingw-w64 toolchain.

If the linker supports it, add the gdb index to the debug symbols, which
makes loading gdb on Qt libraries much faster.

It seems the compiler supports /arch:AVX512 and /arch:AVX512F but none
of the other switches (and neither are documented). And when you pass
those, you also get Conflict Detection (CD), Double & Quad (DQ), Byte &
Word (BW) and Vector Length (VL), which matches the ICC switch
"-xCORE-AVX512". Unlike ICC, there doesn't seem to be an option to
enable only the common part of AVX-512.
Support for Intel Xeon Phi's current features (Exponential &
Reciprocation and Prefetch) and future ones (IFMA, VBMI, 4FMAPS, 4VNNI
and VPOPCNTDQ) seems to be missing altogether.

I need to include linxx/if.h from elsewhere and these two files conflict
by defining the same types (struct ifreq, struct ifmap, struct ifconf,
etc.)

This definition causes a build error if concrt.h is included.
According to Microsoft [1], this macro is unsupported. It was added in
f5908363 to silence compiler warnings that are generated when exceptions
are turned off and certain STL headers are included.
We specifically disable the warnings in question now.
