Implemented c_code for AdvancedSubtensor1
Removed an empty line.  Should kick off travis build.
Fix compilation crash on GPU.

We tried to use the CPU code for the GPU op.

Corrected a typo.
Run basic take() test with and without the sum to allow testing preallocated  output.
Per @lamblin, the sum is not necessary since gh-1187 has been merged.
Trying to fix travis build failures.  Make indices explicit 32-bit int array.
Resubmit failing test to travis with additional diagnostic.
Added an explicit cast in c_code for AdvancedSubtensor1 Op to match logic in perform() and avoid test failures
on 32 bit platforms.  The real issue seem to be that x.shape is a 64-bit tensor regardless of the size of platform's
 size_t type.  This leads to int64 type appearance in any computation involving shape and resulting index cannot
 be passed back to numpy.take() necessitating the cast.
Reverted travis config changes.

Issue #1185 (Implemented c_code for AdvancedSubtensor1): Do not cast if indices array already has correct dtype.
