Description Ryan Haddad 2021-07-16 15:12:34 PDT 
Multiple tests are failing on the Apple-BigSur-AppleSilicon-Debug-JSC-Tests bot

** The following JSC stress test failures have been introduced:
	microbenchmarks/bit-test-constant.js.ftl-no-cjit-fuzz
	microbenchmarks/bit-test-load.js.ftl-no-cjit-fuzz
	microbenchmarks/bit-test-nonconstant.js.ftl-no-cjit-fuzz
	microbenchmarks/get-and-put-by-val-double-index-dont-fall-off-a-cliff.js.ftl-no-cjit-fuzz
	microbenchmarks/get-by-val-polymorphic-ic-4.js.ftl-no-cjit-fuzz
	microbenchmarks/implicit-bigswitch-indirect-symbol.js.ftl-no-cjit-fuzz
	microbenchmarks/int52-rand-function.js.ftl-no-cjit-fuzz
	microbenchmarks/memcpy-typed-loop-large.js.ftl-eager-no-cjit
	microbenchmarks/memcpy-typed-loop-large.js.ftl-no-cjit-fuzz

Looks like they are all timing out:
microbenchmarks/bit-test-nonconstant.js.ftl-no-cjit-fuzz: Timed out after 339.000000 sec seconds!
microbenchmarks/bit-test-load.js.ftl-no-cjit-fuzz: Timed out after 339.000000 sec seconds!
