perform convolution properly independently of matrix orientation (bug #34893)
* cconv2.f (cconv2i), csconv2.f (csconv2i), dconv2.f (dconv2i),
sconv2.f (sconv2i), zconv2.f (zconv2i), zdconv2.f (zdconv2i): Fix
iteration over the a matrix, so it's properly reversed.
* conv2.cc: Uncomment test to check for this, and add a new xtest.
