In latest versions of Windows, one can use VirtualAllocFromApp also
without CodeGeneration flag being set. In conjunction with the new
garbage collector that let to the situtation that the gc tried to
reserve using VirtualAlloc, then the V4Engine constructor checked for
JIT availability and disable JIT. This lead to VirtualAllocFromApp
alloced memory could not be used anymore and caused to a crash latest
when trying to commit or release.
With WinRT 8.1 being removed, we do not need the mem_align version
anymore and can stick with VirtualAllocFromApp/Free, with the JIT check
only testing VirtualProtectFromApp.

Don't try to instantiate the presumed "cross-assembler" twice, and also
exclude the Yarr JIT from the devtools build. It requires a loadPtr
enabled assembler (disabled in V4_BOOTSTRAP builds) and we don't need
the regexp engine.

The use of wildcards in SOURCES is an unspecified "feature" and
it turns out that it doesn't work when doing option(host_build)
and cross-compiling. We could use $$files(), but there is no
truly good reason for using it for only some directories and not
others, so this is now a manual expansion.

Even when the C++ target is not ARMv7 we want to include it in order to
be able to generate QML cache files with code ahead of time.
This requires a few changes:
* The Jump classes need to move from the AbstractMacroAssembler
super-class into the concrete assembler sub-class, in order to
use it in specializations.
* Some of the template specializations in LinkBuffer for example or
for platform dependent operations need to be pre-processor enabled
when bootstrapping
* The generic loadPtr/addPtr etc. functions need to move to the concrete
assemblers to be able to call the correct 32-bit or 64-bit variations.
* We need to force what looks like a loss of precision to the compiler
in the 32-bit ARMv7 linking code when linking jumps.
Finally then we can explicitly instantiate at least QV4::JIT::Assembler
for ARMv7 when bootstrapping. Currently only on x86-64 hosts, but that
is a temporary limitation.

Since the #ifdef for ARMv7 and ARM64 makes it impossible to cross
compile, we need to replace it with a template specialization of
LinkBuffer. The "old" LinkBuffer becomes LinkBufferBase, then there's a
generic LinkBuffer that's a sub-class of LinkBufferBase. Then there's a
BranchCompactingLinkBuffer template that implements the compaction and
two ARMv7 and ARM64 specializations of LinkBuffer<T> end up being
sub-classes of BranchCompactingLinkBuffer instead of LinkBufferBase.

This fix builds on commit f656fc588bab4104d531cb46836168da6736a518
from 22 April 2016 which conditionally includes missing
math functions for Visual Studio older than 2013.
log2 and log2f functions have not been included in the fix because
there was no name conflict in Qt lib itself, but the problem
becomes prominent when trying to link an application simultaneously
to libucrt.lib and qt built with -static -static-runtime options.
This fix corrects following linking issues:
Qt5Qml-static.lib(qv4value.obj) :
error LNK2005: _log2 already defined in libucrt.lib(log2d.obj)
Qt5Qml-static.lib(qv4dateobject.obj) :
error LNK2005: _log2 already defined in libucrt.lib(log2d.obj)
Qt5Qml-static.lib(qv4runtime.obj) :
error LNK2005: _log2 already defined in libucrt.lib(log2d.obj)
Qt5Qml-static.lib(qv4globalobject.obj) :

Qt5Qml-static.lib(qv4jsonobject.obj) :
error LNK2005: _log2 already defined in libucrt.lib(log2d.obj)
This fix has been previously committed to dev branch for review
but was recommended to use branch 5.6, same as referenced commit.
