7e85e7ced7 Add initial clang-cl support to Qt
This adds the functionality to build Qt with clang under Windows against
the Microsoft Visual Studio 2015 runtime.

In order to replicate this, a Clang 3.8 build with Visual Studio 2015
Update 1 is needed.

Adds compiler detection to Qt to distinguish correctly the clang compiler
and Windows with Visual Studio.

Clang has some built-in numeric functions, there is no need to use the
Microsoft versions, which also conflict here.

69ab280315 qmake: optimize container usage in the json handling.
Iterate only once over QJsonObject, create key list by
existing loop instead of create by QJsonObject::keys(),
which contains internal loop.
In common case if loop's statement is lightweight,
then effect of optimization is significant, and vice versa.
Also make addJsonArray() and addJsonObject() functions
more homogeneous.

Use reserve to optimize memory allocation.

fdfd63053a QtBase: avoid uses of Java-style iterators [QHash, QMap]
Java-style iterators are slower than STL-style ones, so
they should not be used in library code.

Replaced them with C++11 range-for, STL iterators or, in
one case, qDeleteAll().

In one case, avoid a double hash lookup by using erase(it)
instead of remove(it.key()), which we can now do without
detaching, due to the new erase() taking const_iterator.

5af12dae41 qmake: replace a QLinkedList with QVector
In VcprojGenerator::collectDependencies(), a temporary QLinkedList
is created, then iterated over. There's no reason to use a node-
based container here: no references are taken, no erases happen,
esp. not in the middle...

Port to QVector instead and reserve it, since the maximum size is
known ahead of time, and the lifetime of the container is very
short.

Since the loop iterating over the linked list needed touching
anyway, port directly to C++11 range-for.

... by replacing them with C++11 range-for loops.

This is the simplest of the patch series: Q_FOREACH took a
copy, so we do, too. Except we don't, since we're just
catching the return value that comes out of the function
(RVO). We can't feed the rvalues into range-for, because
they are non-const and would thus detach.

f33c6f37a8 Work around MinGW-make's magic prefixing of paths.
When building QNX on MS-Windows, make magically adds the Msys root as
prefix to variables whose values look like paths; this applies to both
environment variables and variables given values on the command-line.
When we don't actually want to install under the Msys root, this is
unwelcome "help".  So (for MinGW's make) support a magic prefix of our
own, @msyshack@, that'll make a path value for INSTALL_ROOT not look
like a path to make; we can then strip it off when we come to use it.

c3376ed3f9 winrt: enable hardware buttons for Windows 10
Previously the hardware and camera button handler were guarded inside a
Q_OS_WINPHONE which does not apply to Windows 10.

Instead use WINAPI_PARTITION_FAMILY like on other places, this covers
Windows Phone 8.1 as well as Windows 10.

To find windows.phone.ui.input.h at build time the Mobile Extension
directory needs to be added to the include paths inside qmake. On
runtime we need to check whether we have hardware buttons or not. In
case they exist, register the handlers, otherwise skip registration.
Skipping also helps to keep WACK succeeding.

282f15feaa rewrite qtAddToolEnv()
the primary purpose is making env var prepend mode work for unset
variables on windows. this is achieved by using a conditional and delayed
variable expansion. however, the latter is disabled by default and can
be locally enabled only in batch files. therefore, write wrapper scripts
and substitute them for the actual commands. we do this also on unix,
both for consistency and simply because the commands look much less
confusing.

this change is slightly backwards-incompatible, as invoking
qtAddToolEnv() multiple times on the same command will now make a total
mess. also, invoking it on a command that contains 'make' macro
expansions isn't a good idea, so testcase.prf needed an adjustment. the
function is an undocumented internal, so Nobody Should Care (TM).

this also reverts 80ebedecf9, as it's obsolete now.

64ab4de4b0 Teach qmake's #include parser to recognize C++11 Raw strings.
Can't sensibly test unless the compiler does support raw strings,
since any test that would catch qmake's (prior) inability to parse raw
strings would necessarily confuse the C++ compiler in the same way.
This even applies (in test app code) to any #if-ery around the raw
string, since tokenization happens before preprocessor directives are
resolved.  So the #if-ery on Q_COMPILER_RAW_STRINGS has to be in
tst_qmake.cpp, not the test app it builds.

cbb2ce0f91 Remove Wow6432Node versions of Visual Studio registry keys
The Visual Studio registry keys are stored in the 32 bit view.
Extend qt_readRegistryKey with an option that enables the caller to
choose the 32 bit or 64 bit registry view.
We now read the Visual Studio registry keys from the 32 bit registry
view even in a 64 bit build.
Adding the next Visual Studio version will become a bit easier.
