assert: make comparisons file more performant

[puskin]

As part of my ongoing review of the assert codebase, I started examining the comparisons.js file and optimizing some straightforward code that could be further refined for better performance.

Here are the benchmark results for the assert/deepequal-simple-array-and-set.js file:

OLD:

assert/deepequal-simple-array-and-set.js method="deepEqual_Array" strict=1 len=10000 n=500: 8,398.503339673252
assert/deepequal-simple-array-and-set.js method="notDeepEqual_Array" strict=1 len=10000 n=500: 8,365.394964343424
assert/deepequal-simple-array-and-set.js method="deepEqual_Set" strict=1 len=10000 n=500: 14,487.154442975576
assert/deepequal-simple-array-and-set.js method="notDeepEqual_Set" strict=1 len=10000 n=500: 14,514.332017493021

NEW: 

assert/deepequal-simple-array-and-set.js method="deepEqual_Array" strict=1 len=10000 n=500: 8,470.789541116153
assert/deepequal-simple-array-and-set.js method="notDeepEqual_Array" strict=1 len=10000 n=500: 8,443.200479573787
assert/deepequal-simple-array-and-set.js method="deepEqual_Set" strict=1 len=10000 n=500: 8,962.574475856993
assert/deepequal-simple-array-and-set.js method="notDeepEqual_Set" strict=1 len=10000 n=500: 10,943.39339352156

a performance improvement of 25-38% can be noticed in the sets tests
