3ed67cb0bb Fix a bug in the implementation of Carmack's fast sqrt algorithm in Eigen (enabled by EIGEN_FAST_MATH), which causes the vectorized parts of the computation to return -0.0 instead of NaN for negative arguments. 
Benchmark speed in Giga-sqrts/s
Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz
-----------------------------------------
                    SSE        AVX
Fast=1              2.529G     4.380G
Fast=0              1.944G     1.898G
Fast=1 fixed        2.214G     3.739G

This table illustrates the worst case in terms speed impact: It was measured by repeatedly computing the sqrt of an n=4096 float vector that fits in L1 cache. For large vectors the operation becomes memory bound and the differences between the different versions almost negligible.

9d6d0dff8f bug #1317: fix performance regression with some Block expressions and clang by helping it to remove dead code. 
The trick is to get rid of the nested expression in the evaluator by copying only the required information (here, the strides).

fe29157d02 disabled MSVC level 4 warning C4714 
The level 4 warning (/W4) warns about functions marked as __forceinline not
inlined, and generates a lot of noise.

50e3bbfc90 Calls x.imag() instead of imag(x) when x is a complex number since the former 
is a constexpr while the later isn't. This fixes compilation errors triggered by nvcc on Mac.
