  PLASMA_cgesv_incpiv_Tile - Solves a system of linear equations using the tile LU factorization. Tile equivalent of PLASMA_cgetrf_incpiv(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors. Parameters
  [in,out] | A | On entry, the N-by-N coefficient matrix A. On exit, the tile L and U factors from the factorization (not equivalent to LAPACK).
  [in,out] | L | On exit, auxiliary factorization data, related to the tile L factor, necessary to solve the system of equations.
  [out] | IPIV | On exit, the pivot indices that define the permutations (not equivalent to LAPACK).
  [in,out] | B | On entry, the N-by-NRHS matrix of right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X.
  Returns Return values
  PLASMA_SUCCESS | successful exit
  >0 | if i, U(i,i) is exactly zero. The factorization has been completed, but the factor U is exactly singular, so the solution could not be computed.
