[InstCombine] Canonicalize icmp instructions based on dominating conditions.
Summary:
This patch canonicalizes conditions based on the constant range information
of the dominating branch condition.
For example:
%cmp = icmp slt i64 %a, 0
br i1 %cmp, label %land.lhs.true, label %lor.rhs
lor.rhs:
%cmp2 = icmp sgt i64 %a, 0
Would now be canonicalized into:
%cmp = icmp slt i64 %a, 0
br i1 %cmp, label %land.lhs.true, label %lor.rhs
lor.rhs:
%cmp2 = icmp ne i64 %a, 0
