The script will look for the most recent Qt Creator version on the system,
and pick up the LLDB summary providers from there, allowing pretty-printing
of Qt types inside LLDB/Xcode.
LLDB will detect the file when loading the dSYM, and inform the user that
the file can be loaded to enable the formatters. The script can be loaded
automatically by adding the following setting in ~/.lldbinit:
settings set target.load-script-from-symbol-file true
Which comes as a slight security risk, as other libraries might have
scripts of their own. The alternative is to load the script directly
from ~/.lldbinit:
command script import "<path to debug script in dSYM>"
With an optional target.load-script-from-symbol-file set to false, to
silence the warning when loading the dSYM bundle.

With 4183475080, Qt fails to build if
qmake is unable to detect the compiler's default include and
library search paths. Clang on non-Darwin systems was missing working
code for the detection.
Unlike GCC, Clang on its own does not print the library search paths
when called with the -v option.
On Darwin, the -Wl,-v option will reach ld64, which will print those paths.
However, neither GNU ld nor gold will print anything useful with just
-v. GNU ld has a --verbose option that does print some search paths, but
those are not the ones used when ld is invoked (via collect2) by GCC or
Clang, so it can't be used.
To make Clang print its library search paths one can use
-print-search-dirs, which however doesn't print include search paths. So
amend the existing code in order to make a second call to clang on
non-Darwin systems. This second call is used for library path detection,
and fixes the build on non-Darwin (tested on Linux).

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 .pro file requires the QMAKE_CFLAGS_F16C to be set to something. So
set it to AVX, as the instructions require the VEX prefix anyway (ICC
has no dedicated option for just 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.

The font database uses UIKit symbols on all UIKit platforms and thus it
must be linked to. Also, limit the missing CoreText.h workaround so
that it is not applied for versions of Xcode where the bug is fixed.

The compiler is mostly GCC in disguise, but the libraries are not. Since
the toolchain is not open, it's difficult to fix issues in it.

the target of the injected forwarding header doesn't exist at qmake
time, as it is generated by an extra compiler, so the touch() calls in
qt_module_headers.prf would fail.
the error scenario described in ce942a226 is not applicable to
gui/vulkan, as no bootstrapped modules are involved. therefore, we can
just suppress the timestamping.

the borrowing of headers always happens from "proper" modules which are
actually built as frameworks if so requested. that means that even
though the borrowing module itself never is a framework, it needs a
framework path and include paths that point into frameworks.

Introduce QPA-based Vulkan library loader, core function resolver, and
instance creation support. In addition to creating a new VkInstance,
adopting an existing one from an external engine is supported as well.
The WSI specifics are hidden in the platform plugins. Vulkan-capable
windows use the new surface type VulkanSurface and are associated with
a QVulkanInstance.
On Windows VULKAN_SDK is picked up automatically so finding vulkan.h
needs no additional manual steps once the LunarG SDK is installed.
