b038a4bb71 * added EIGEN_ALIGNED_ALLOCATOR macro to allow specifying a different aligned allocator 
* attempted to add support for std::deque by copying and modifying the std::vector implementation...MSVC still fails to compile with the std::deque::resize() "will not be aligned" error...probably missing something simple but I'm not sure how to make it work

d9e134c73c Altivec port of Complex.h. 
Note: For some reason g++ 4.4 is >200% slower than g++ 4.3 on altivec code.
The same benchmark (bench_gemm) was tested, on the same hardware/OS (G4/Debian testing),
with same CFLAGS. With some code reorganizing I managed to get some minor gain
on 4.4, but I just could not reach 4.3 speed. This is most likely a bug, but I'm waiting
to see if it's fixed on 4.5. I'll look into this a bit more.

42c62c8876 fix #126, part 2/2: the checkTransposeAliasing() assertion was always compiled, for all expressions, 
even for expressions that are known at compile time to not need it because they don't involve any transposing.
This gave 'controlling condition is constant' warnings on ICC, and potentially worse, this could generate a lot
of useless code per-expression if the compiler failed to realize that the condition was constant.

c21390a611 Define non-const operator() in Reverse; enable test for this. 
Introduction of DenseCoeffBase (revision bfdc1c4973
) meant that non-const
operator() is only defined if DirectAccess is set. This caused the line
"m.reverse()(1,0) = 4;" in MatrixBase_reverse.cpp to fail at compile-time.
Not sure this is correct solution; perhaps we should disallow this? Or make
Reverse DirectAccess with a negative stride - would that break something?
