This commit fixes a bug in the function compute_const_folding_using_tf where an already-folded StridedSlice node could set the 'update' flag to True, causing an infinite loop.
A regression test was also added. The test checks for the infinite loop by setting a timeout using the timeout-decorator module from pypi.
This should fix issues #2068 and #1965 .
