Bug 712837 - Remove flakey test js1_5/extensions/regress-371636.js; r=dmandelin

In the test js1_5/extensions/regress-371636.js, we time a loop over an Array
using Numbers as keys, then do the same loop again using Strings as keys.  The
test asserts that the time using Strings is less than 3 times as large as the
time using Numbers.  Naturally, when running the tests with high parallelism,
this tends to fail at random.  Since losing this optimization would be an
extremely serious perf bug, we would notice this immediately from our perf
tests.  There is no reason to keep this as a correctness test.
