Earlier versions of the compiler cannot default
move special member functions, even though we
also define Q_COMPILER_RVALUE_REFS for them.
Fix by retracting the less-often-used of the
two compiler feature defines.
Q_COMPILER_DEFAULT_MEMBERS is not used outside
QtBase in neither 5.6 nor 5.7 (5.8 is not
released at this time, so wasn't considered).
The same is true of the dependent macros
Q_COMPILER_DEFAULT_DELETE_MEMBERS and
Q_DECL_EQ_DEFAULT.
In QtBase, the three uses are:
1. in QAtomic*, where the user also requires
Q_COMPILER_CONSTEXPR, which is not defined
for any MSVC at this time,
2. for QEnableSharedFromThis, which is a class
template with an alternative {} implementa-
tion of the default constructor, and uncon-
ditional user-defined copy special member
functions.
3. The test of the corresponding functionality
in tst_compiler, which this commit amends.
That means that neither of these two only uses
of the macro in Qt libraries are affected by
the change.
The reason we do this change, then, is that in
the future, we want to be able to more easily
restore move special member functions for
classes for which they are suppressed due to
user-defined dtors or copy special member
functions.

If the compiler supports C++11 alignof, let's use it. No point in
perpetuating the use of __alignof__ or __alignof.
There's a fallback implementation in qglobal.h that works even without
compiler extensions. We can't drop it just yet (alignas is not a
required C++11 feature), but at this point I doubt that fallback is used
anywhere anymore.
The tst_compiler test was wrong to use alignof(variable). That's not
permitted by the standard nor would it work with our fallback
implementation. MSVC 2015 enforces this, but ICC, GCC and Clang don't.

Check that we can use std::forward, and that the compiler
synthesizes move special member functions when it should.
MSVC only supports the latter since the Nov 2013 CTP,

of N2346, hence default and delete functions are supported only if they

modifier is not relevant. Compiler error:

Remove the -armfpa option the config.tests/unix/doubleformat*
detection. The places where we used QT_ARMFPA and Q_DOUBLE_FORMAT
has been removed as well.
Rationale: ARM FPA with GCC does not work with EABI. Qt currently
does not support compiling without EABI, making ARM FPA an
impossibility. It is unknown whether other compilers provide ARM FPA
support with EABI. Support for ARM FPA can be re-added in the future
should the need arise, but since ARM VFP is available for ARMv5 and up,
we should encourage implementors to instead use soft-floats or VFP.

Reusing a template is much better then creating a new one, even if it

For some reason replacing T* by void* force gcc to remove a few bytes
per template instantiation too, it is not really significant, but it
alows us to simplify the code.
Benchmarks don't show any regressions.
