Support selective 64-bit mumps
A standard installation of MUMPS supports selective 64-bit. It uses int64_t for number for nonzeros (i.e., id.nnz, id.nnz_loc), and use int for indices of nonzeros (i.e., id.irn, id.jcn, id.irn_loc and id.jcn_loc).
Previously, one can only build petsc with 32-bit indices to work with mumps.
This commit updates MUMPS interface to work with 64-bit-indices petsc.
