Andreas proposed to check

There is really no reason for the case ( INFO.LT.0 ) to happen, so we should
not have to deal with this case.  If this happen, it is really a bug and we

(2) add a quick return for N=1

(3) no one reviewed this fix, feel free to comment

Dear LAPACK people,

I found a bug concerning the following function:

The xGETC2 is the level-2 BLAS implementation of an LU decomposition
with complete pivoting. Thereby, a "comparison depending on an
uninitialized value" appears if the input is an one-by-one matrix.
Namely the code in line 202 (LAPACK 3.5.0):
    IF( ABS( A( N, N ) ).LT.SMIN ) THEN
accesses SMIN which is set in the previous DO loop. This loop is
only called if N > 1 and so SMIN is not set to a well defined value
if N = 1. But the documentation claims that all matrix N>=0 are
allowed. Furthermore if calling with N = 0 the quick return
statement is missing and the evaluation of ABS(A(N,N)) then yields
an out-of-bound memory violation.

These bug affect the real and the double precision code as well
as their complex counterparts from LAPACK 3.0 up to the current
LAPACK 3.6.

regards,
Martin Köhler

In ?syconv, replace the variable name WORK by the variable name E.  E is the
standard way to name the supdiagonal/subdiagonal of a symmetric tridiagonal

The subroutine DSYCONV stores the supdiagonal of the symmetric 1-by-1 or 2-by-2
block matrix in the array WORK. (Or the subdiagonal, same array.) Before
commit, only the nonzero elements of WORK were initialized to their correct
nonzero values. The zero entries were not initialized and not referenced and
assumed to be zero in subsequent subroutines. This is fine, but I think a
better behavior for the subroutine is to initialize these zero entries to zero.
So the commit is initializing these entries to zero.

Also a (double precision) ZERO in the D routine should have been an (integer)
0.

Also fix some formatting to have C, D, and S consistent.

Note: the indentations, comments of the Z routine is not consistent with C, D and
S. I did not have time to fix this.

When LAPACK_NAN_CHECK is enabled, in input of xLASET, we now allow if the matrix A contains NaN.

Since the goal of xLASET is to set values in A, we consider it OK if A contains NaN in input.

In other words, the rationale is that we do not consider A has an input/output. We consider A as an output only.

Note: We allow neither alpha nor beta to be a NaN.

(So we do check for NaN in alpha and in beta and return error if NaN.)

(1) removes the NaN check on matrix A in LAPACKE wrappers: lapacke_?laset.c
