[JSC] Store 1 byte instead of 4 in didEnterVM for validateDFGClobberize
https://bugs.webkit.org/show_bug.cgi?id=305771
rdar://168448595
Reviewed by Mark Lam.
When generating code for --validateDFGClobberize, write only 1 byte instead of
4 into vm.didEnterVM, as storing 4 bytes would overwrite neighboring bools.
