Sanjoy Das dcf2651043 Teach IRCE to look at branch weights when recognizing range checks 
Splitting a loop to make range checks redundant is profitable only if
the range check "never" fails. Make this fact a part of recognizing a
range check -- a branch is a range check only if it is expected to
pass (via branch_weights metadata).
