Title: RFC:Various small fixes initiated by update of linalg tests

Update of linalg tests to go through all four Lapack types and removed some extra complex tests. As a consequence, some changes in Lapack.jl for Float32 and complex types. Some fixes of return type in linalg. Some changes to Tridiagonal, but more work is needed here. Change of criterion in check_approx_eq to take float precision into account. This affects other tests. Hence I have added precision to the true values in the math test. Also, the return type in irfft has been corrected but in a very ugly way. Finally, change of eig to use new fast solver for symmetric problems.
