5ad8b9bfe2 Make inverse 3x3 faster and avoid gcc bug. 
There seems to be a gcc 4.7 bug that incorrectly flags the current
3x3 inverse as using uninitialized memory.  I'm *pretty* sure it's
a false positive, but it's hard to trigger.  The same warning
does not trigger with clang or later compiler versions.

In trying to find a work-around, this implementation turns out to be
faster anyways for static-sized matrices.

154f00e9ea Fix inverse nullptr/asan errors for LU. 
For empty or single-column matrices, the current `PartialPivLU`
currently dereferences a `nullptr` or accesses memory out-of-bounds.
Here we adjust the checks to avoid this.

12e8d57108 Remove pset, replace with ploadu. 
We can't make guarantees on alignment for existing calls to `pset`,
so we should default to loading unaligned.  But in that case, we should
just use `ploadu` directly. For loading constants, this load should hopefully
get optimized away.

This is causing segfaults in Google Maps.

eb46f34a8c Speed up 2x2 LU by a factor 2, and other small fixed sizes by about 10%. 
Not sure that's so critical, but this does not complexify the code base much.

15e53d5d93 PR 567: makes all dense solvers inherit SoverBase (LU,Cholesky,QR,SVD). 
This changeset also includes:
 * add HouseholderSequence::conjugateIf
 * define int as the StorageIndex type for all dense solvers
 * dedicated unit tests, including assertion checking
 * _check_solve_assertion(): this method can be implemented in derived solver classes to implement custom checks
 * CompleteOrthogonalDecompositions: add applyZOnTheLeftInPlace, fix scalar type in applyZAdjointOnTheLeftInPlace(), add missing assertions
 * Cholesky: add missing assertions
 * FullPivHouseholderQR: Corrected Scalar type in _solve_impl()
