Title: Alignment and performance

* Use a default alignment depending on the SIMD instruction set
* Use also the default alignment in the Matx template (note: the performance improvement seen in some of my projects is of importance)
* Add an optional argument to the inv() method of Matx to be able to check the success of this operation without any additional operation

See Issue #3224.
