Fix matrix initialization in triangular timings

This PR replaces !112 (closed) as this last one was introducing an issue with the Cholesky checking. It tries to minimizes the matrix A initialization to a single triangular part if both sides of the matrix is not required. Note that for now, checking is using a GEMM operation and thus requires both sides of the original symmetric/hermitian matrix to be initialized.
