isl_basic_map_remove_divs_involving_dims: insert bounds before removing divs

The div will be removed using Fourier-Motzkin elimination and the extra
bounds can be used to improve accuracy of the result.

For example, eliminating the div from the following set

{ [i,j,k] : 3 + i + 2j >= 0 and 2 * [(i+2j)/4] <= k }

we now first use the first constraint to derive a lower bound
on the div:

[(i + 2j)/4] >= [-3/4] = -1

During the elimination, this bound can be combined with the upper bound
to result in the additional constraint

k >= -2

Although this technique can be applied in general, it is especially
useful after the next commit, where we will eliminate divs
that appear with a unit coefficient.  If the same div also appears
in other constraints with a non-unit coefficient, and we later
decide to eliminate the div, then this technique can be used to
recover some of those constraints so that we can avoid losing accuracy.

isl_hash.c: reset the number of entries to 0 when growing the hash table

The hash table is grown by creating a new table and adding the entries
of the old table to the new table.  Since the new table starts out as
being empty, the number of entries should be reset to 0.

Not only would the old code result in isl_union_map_n_map returing
the wrong value if the underlying hash table had ever been grown,
it would also result in the table subsequently being grown again
far too early.

isl_tab_basic_map_partial_lexopt: don't normalize intermediate div expressions

The function get_row_parameter_div would call normalize_div before finishing
the construction of the div expression.  In particular, it would call
normalize_div before negating the coefficients.  Since normalize_div may round
down the constant term, the result of first normalizing and then negating
may result in a different div than first negating and then normalizing.
Call normalize_div only after negating the coefficients.
