Add thread polling on backedges of Range#each loop

[headius]

There are several forms of loops here but none had any explicit
thread polling, which led to #7279 and timeout events not firing
during trivial Range#each loops. This commit adds polling to all
loops reachable from Range#each, which fixees #7279 and other
untested cases.

This does, however, come with a performance hit; the related thread
state must be checked after each loop. These could be improved in
the future by using a safe point mechanism like SwitchPoint, or by
porting these functions to Ruby which gets backedge thread polling
via the IR.

Fixes #7279

Certainly, this change affects performance.

@headius @k77ch7 We could try and measure impact but we can also opt for callThreadPoll() which will only poll every 0xFFF calls. We could also customize modulos how many backedges to pass to check? I think it is important to see if this impact is something we would really notice or not though. Looks like this will do 2 native calls and one field read.

I try and measure impact. There may be no practical impact.
I think we can merge.

Test script

n = 10000000
Benchmark.bm do |x|
  5.times do 
    x.report do 
      100.times do
        for i in 0..n do; (i + i % (i+1)) % (i + 10) ; end
      end
    end
  end
end

@k77ch7 Thank you! I agree, the impact seems minimal.
