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.

It's easier to parse than qglobal.h. The objective is actually to have
macros with parts of the version number, so the major or minor numbers
could be used in other preprocessor macros.

We've been setting the -Zm argument since the dawn of times (even before
the first git commit). Anyhow, MSDN from VS2008 onwards indicates
that this is not needed:
"In earlier versions of Visual C++, the compiler used several discrete
heaps, and each had a finite limit. Currently, the compiler dynamically
grows the heaps as necessary up to a total heap size limit, and requires a
fixed-size buffer only to construct precompiled headers. Consequently, the
/Zm compiler option is rarely necessary."
[ChangeLog][Compiler Specific Changes] Visual Studio: -Zm200 (an option to
specify the precompiled header memory allocation limit) is not added anymore
by qmake to the compiler calls. If you encounter an C1076 compiler error you
might need to re-add it in your .pro file.

The static CRT, libcpmt.lib, is not shipped with Visual Studio Express
for Windows (unlike VS Express for Windows Desktop or Professional
versions), causing configure and qmake to fail linking if this is the
only VS installed. By removing -MT (which is on by default) and adding
$(CFLAGS_CRT) to the compiler line, -MD can be added to the compiler
flags via the environment, providing a workaround for the issue.

When MSVC supports ref-qualified members, we need to ensure that
qstring_compat.cpp can see the non-qualified definitions in qstring.h,
which means no precompiled header.
Alternatively, for a bootstrapped build we could not compile
qstring_compat.cpp or #ifndef the functions.

This is the first step in implementing an in-place conversion of QString
to QByteArray. This requires ref-qualifiers in member functions so we
know that we have an rvalue QString.
Converting from UTF-16 to Latin1 always requires half the memory.
For conversion from UTF-16 to UTF-8, the typical string will also need
the same memory or less: characters from U+0000 to U+007F consume one
fewer byte; characters from U+0080 to U+07FF and from U+10000 to
U+1FFFFF occupy the same space in UTF-8 and UTF-16; it's only the ones
from U+0800 to U+FFFF that consume more space in the UTF-8 string.
For the locale's 8-bit codec, we can't be sure and the code (currently)
needs to go through QTextCodec anyway.
This requires a #define set before #include'ing "qstring.h". However,
since qstring.h is included by the QtCore PCH, we need an extra qmake
compiler without the PCH flags to compile this .cpp.
After this change, the distribution of calls in QtCore, Network, Gui,
and Widgets is as follows:
const & &&
toUtf8 31 (74%) 11 (26%)
toLatin1 79 (77%) 24 (23%)
toLocal8Bit 26 (16%) 138 (84%)
