Cannot finish web-tooling-benchmark test

I'm trying to run web-tooling-benchmark on ChakraCore (version in master branch) but it seems that it just stuck at coffeescript test and cannot finish the entire test:

ch cli.js

Output (stuck at coffeescript test and not able to get the test result):

(stuck here)

While using v8 with node 14:

Prebuilt test suite: dist.zip

Also I think this can be added into ChakraCore benchmark test #6431

This is a bug - in a debug build it hits an Assertion, in a release build it gets stuck in an infinite loop, going to be a pain to work out what the underlying cause is.

This is the Assertion: https://github.com/chakra-core/ChakraCore/blob/f5296a1bfdb619ec55d2cbf909ee7747d35939c5/lib/Backend/DbCheckPostLower.cpp#L81
