eigvals: vh not defined error on SymTridiagonal matrices

[jiahao]

eigvals() throws a vh not defined error when using it to compute eigenvalues of a SymTridiagonal matrix. For example:

e=randn(5);
f=randn(4);
M=SymTridiagonal(e,f)
eigvals(M)
ERROR: in eigvals: vh not defined
 in eigvals at linalg/tridiag.jl:50
 in eigvals at linalg/tridiag.jl:51

eig(M) works just fine, as does eigvals(M) for a dense matrix M.

Reported on latest HEAD version (be3835e), OSX 10.8.3

@andreasnoackjensen The eigvals for SymTridiagonal looks funny. There are two definitions with the same signatures and they are using variables that are not passed in.

I think I fixed it...
