Max Kazantsev d9aee3c0d1 [IRCE] Support narrow latch condition for wide range checks 
This patch relaxes restrictions on types of latch condition and range check.
In current implementation, they should match. This patch allows to handle
wide range checks against narrow condition. The motivating example is the
following:

  int N = ...
  for (long i = 0; (int) i < N; i++) {
    if (i >= length) deopt;
  }

In this patch, the option that enables this support is turned off by
default. We'll wait until it is switched to true.
