------------------------------+---------------------------------
In this ticket we reimplement all of matrix_integer_dense using FLINT
fmpz_mat_t.
The speed-up is substantial. With the new code:
{{{
sage: A = Matrix(ZZ,1000,1000,range(10^6))
sage: %time B = A*A
CPU times: user 883 ms, sys: 3.33 ms, total: 887 ms
Wall time: 888 ms
}}}
This takes more than 1 minute in the same computer using Sage 6.3.
