  BUG: Make type_tuple_type_resolver more robust.

When a loop match fails on account of casting, continue searching the
loops until success or all loops have been examined. The failure to do
this was causing true_divide to fail with float inputs and dtype=float
because the first loop found was (int8, int8, float64), leading to a
casting error as float cannot be safely cast to int8. Versions of numpy
previous to 1.10 will still fail silently if this is backported as the
casting rules were less strict, so that would also need fixing.

Closes #3484.

  TST: Test that true_divide works for float inputs and dtype=np.float.

This was failing due to the check for matching loops not searching
through all available loops, rather ending with int8 inputs and float
output, which in turn would fail casting.
