Add a SparseCompressedBase class providing (un)compressed accessors (like data()/*Stride() for dense matrices),
...
and a CompressedAccessBit flag (similar to DirectAccessBit for dense matrices).

bug #936 , patch 3/3: Properly detect FMA support on ARM (requires VFPv4)

bug #936 , patch 1.5/3: rename _FUSED_ macros to _SINGLE_INSTRUCTION_,
...
because this is what they are about. "Fused" means "no intermediate rounding
between the mul and the add, only one rounding at the end". Instead,
what we are concerned about here is whether a temporary register is needed,
i.e. whether the MUL and ADD are separate instructions.
Concretely, on ARM NEON, a single-instruction mul-add is always available: VMLA.
But a true fused mul-add is only available on VFPv4: VFMA.

bug #935 : Add asm comments in GEBP kernels to work around a bug
...
in both GCC and Clang on ARM/NEON, whereby they spill registers,
severely harming performance. The reason why the asm comments
make a difference is that they prevent the compiler from
reordering code across these boundaries, which has the effect
of extending the lifetime of local variables and increasing
register pressure on this register-tight code.

gcc doesn't consider that
...
template<typename OtherDerived> TensorStridingOp& operator = (const OtherDerived& other)
provides a valid assignment operator for the striding operation, and therefore refuses to compile code like:
result.stride(foo) = source.stride(bar);
Added the explicit
TensorStridingOp& operator = (const TensorStridingOp& other)
as a workaround to get the code to compile, and did the same in all the operations that can be used as lvalues.
