Handling unordered sparse matrices (as in SparseQR::matrixR)

Version: 3.2

Description

The inner indices in the matrix returned by SparseQR::matrixR are unsorted. This makes any componentwise binary operation (e.g. +) fail as it iterates over the indices.

This appears to be trivially reproducible: construct a sparse matrix; calculate it's QR; look at the inner indices. If it's not, I'm happy to put together an example.
