Improve product kernel: replace the previous dynamic loop swaping strategy by a more general one:
...
It consists in increasing the actual number of rows of lhs's micro horizontal panel for small depth such that L1 cache is fully exploited.

Added support for 32bit index on a per tensor/tensor expression. This enables us to use 32bit indices to evaluate expressions on GPU faster while keeping the ability to use 64 bit indices to manipulate large tensors on CPU in the same binary.

using templates instead of macros and if()'s.

broken. My bad for not testing earlier.
