blas/testblas: fix zsame and adjust tests
...
Previously, the test condition for same-ness of two
complex numbers was wrong. The presence of even a single NaN in the real
or imaginary component of either number made both numbers to be
considered same.
This fix changes the logic so that two complex numbers are considered
same if:
* both numbers have both components NaN
* both numbers have one component NaN and the other is exactly equal
* both numbers have both components exactly equal

floats: add functions for handling NaN payloads
...
This handles the simple case of ignoring sign and only dealing with
quiet NaN values since signalling NaN would require that we check that
at least one of the low bits was set and fail somehow if not.
Note that Go treats all NaNs as silent.

mathext: speed up Digamma for large negative arguments
...
Before the Digamma function could be quite slow for large negative
arguments because it had to do use the recurrence relation thousands
of times. This avoids that by instead using the reflection formula. It
also adds some explicit checks for special cases (Inf, NaN, poles).

* mat: Add RawU method to the Cholesky decomposition to directly expose the storage matrix
This is returned as Triangular rather than TriDense for two reasons
1) In the future, we may be able to optimize Cholesky, for instance by storing the decomposition as a banded matrix if the factorized matrix was banded. Returning as Triangular allows this to be robust to future modifications of Cholesky.
2) Normally one wants to return concrete types to allow maximum flexibility is using them, for example avoiding interface assertions. However, the opposite is true here. The user should not modify the returned data, and by returning a Triangular rather than a TriDense, this forces tricky code in order to be able to modify the returned matrix.
Fixes #270 .
