eliminate use of USE_64_BIT_IDX_T
* common.mk (do_subst_config_vals, do_subst_cross_config_vals):
Don't substitute OCTAVE_CONF_USE_64_BIT_IDX_T.
* toplev.cc (octave_config_info): Set USE_64_BIT_IDX_T from
OCTAVE_CONF_ENABLE_64.
* oct-conf.in.h (OCTAVE_CONF_USE_64_BIT_IDX_T): Delete macro.
* oct-hdf5.h, amd.cc, ccolamd.cc, colamd.cc, dmperm.cc, symbfact.cc,
ov.cc, CSparse.cc, CSparse.h, MArray-i.cc, dSparse.cc, dSparse.h,
SparseCmplxQR.h, SparseQR.h, sparse-base-chol.cc,
lo-array-errwarn.cc, lo-array-gripes.cc, oct-sparse.h, acinclude.m4,
oct-conf-post.in.h, computer.m:
Use ENABLE_64 instead of USE_64_BIT_IDX_T.
