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.
