Don't try to detect the CPUID instruction if we're compiling for Pentium

If we're compiling for Pentium or better CPUs, then we know that the
CPUID instruction is present (I think it was introduced in late 486s,
actually). So don't try to detect it. Simply assume it's there and then
execute it.

This means that if you compile Qt for Pentium (or higher) and run it on
an i386 or i486, you'll get a SIGILL (or whatever your OS produces for
an #UD processor exception). If the CPU detection code even got run --
SIGILL might happen for any other instructions found along the way.

Make sure deprecation warnings don't cause errors with -Werror

It sounds like a good thing to have this warning, but for
future-proofing we can't have it. The system libraries might change
and add deprecation marks (OS X does that often). If they do that, we
don't want poor developers to have to fix all warnings before they can
build Qt again.

Add QJsonValue::toInt().

It's a nice feature to have.

MSVC also complains about using doubles to create enum values, so
the ugly workaround is:

enumValue = MyEnum(qRound(json["myEnumValue"].toDouble()));

[ChangeLog][QtCore][QJsonValue]Added QJsonValue::toInt().

always check for baseEnv init failure

sync up; this doesn't actually do anything in qmake.

creator's file watcher can trigger many parallel, entirely
non-hierarchical project reloads. if there is enough of them to exceed
the thread pool size, some will be serialized already by qtconcurrent,
not by our wait condition. these should notice a faulty spec, too.

lock baseEnv in cache()

sync up; this doesn't actually do anything in qmake.

as we modify the environment, it must be properly locked.
this implies that initFrom() also needs to be called with a lock.

avoid deadlock in cache() during spec/cache loading

sync up; this doesn't actually do anything in qmake.

if we end up calling cache() from within the initialization of the base

before we proceed, obviously.
