Add missing bitwise cast

1

Some bitwise casts functions (from and to unsigned integers) are missing.

batch_bool kernel `equal` method

3

We shoudl do two things: 1. rename equal method to `eq` so that it matches the regular kernels 2. change the implementation in batch_bool_float kernel to use ! not_equal which...

Handle loading of bool* correctly

1

Currently, it's not possible to load from a bool pointer. E.g. ```cpp xt::uvector xbools(100, true); xsimd::load_unaligned(&xbools[0]) ``` fails with substitution errors. Now it's actually a question *what* we should do...

There are some small failures with loading 64bit integers from char for `-arch=nocona` ``` [ RUN ] xsimd.api_load 1: lhs = 67305985 - rhs = 1 2: lhs = 134678021...

Mathematical functions of `xsimd` should accept integral types when their standard counterparts do.

power, trigonometric and hyperbolic tests are failing for NEON instructions because of potential truncation.

JohanMabille

`cvttps` uses truncation and `3/5 == 0` becomes true which seems to be the default behavior in C++

Add arange

1

SIMDified arange can give a ~4x improvement about `std::iota` and for loops.
