Reduced testcase

I have reduced the test as much as I could. Seems it's relevant that there are a bunch of calls to Math.max before the bug (they can be any kind of calls, see the loop), and we need the previous foo() calls for the bug to be triggered. With no DFG the result is correct, with DFG we need the forceEagerCompilation parameters to see the bug:

niraikanai:~/git/WebKit%./WebKitBuild/Debug/bin/jsc --useDFGJIT=false JSTests/ChakraCore/test/jsc-lib.js ~/js/chakra.max.js
