a4098ac676 Fix duplicate include guard *ALTIVEC_H -> *ZVECTOR_H 
Some some header guards were repeated between the `AltiVec` package and the
`ZVector` packages. This could cause a problem if (for whatever reason) someone
attempts to include headers for both architectures.

8eab7b6886 Improve exp<float>(): Don't flush denormal results +4% speedup. 
1. Speed up exp(x) by reducing the polynomial approximant from degree 7 to
degree 6. With exactly representable coefficients computed by the Sollya tool,
this still gives a maximum relative error of 1 ulp, i.e. faithfully rounded, for
arguments where exp(x) is a normalized float. This change results in a speedup
of about 4% for AVX2.


2. Extend the range where exp(x) returns a non-zero result to from ~[-88;88] to
~[-104;88] i.e. return denormalized values for large negative arguments instead
of zero. Compared to exp<double>(x) the denormalized results gradually decrease
in accuracy down to 0.033 relative error for arguments around x = -104 where
exp(x) is ~std::numeric<float>::denorm_min(). This is expected and acceptable.

c06c3e52a0 Include immintrin.h if F16C is available and vectorization is disabled 
If EIGEN_DONT_VECTORIZE is defined, immintrin.h is not included even if F16C is available. Trying to use F16C intrinsics thus fails.

This fixes issue #2395.

f7a056bf04 Small fixes 
This MR fixes a bunch of smaller issues, making the following changes:

* Template parameters in the documentation are documented with `\tparam` instead
  of `\param`
* Superfluous semicolon warnings fixed
* Fixed the type of literals used to initialize float variables
