AdvancedSubtensor1 support for local_useless_subtensor optimization

Add a way for almost-equal types replacements to be patched over automatically.

Fix the problem with partial set_subtensor coverage in gpuarray.

Added GpuDownsampleFactorMaxGradGrad

Faster tests in DebugMode and more resistent to rounding difference.

This is a guess to try to fix strange return value for gpu_int_ptr

Feature for no outputs from inplace.

Crash fix and simpler graph

Move values_eq_approx outside of function to allow pickling

Crash unpickle

max_pool_2d stride support

Better error message when the test_value do not have the right type

Remove coverage from the daily buildbot. We don't use it, it make the output very big and if we want to use it, now there is better online tools that integrate with github
