Combine expression patterns to form expressions with fewer, simple instructions.
-This pass does not modify the CFG.
For example, this pass reduce width of expressions post-dominated by TruncInst
into smaller width when applicable.
-It differs from instcombine pass in that it contains pattern optimization that
-requires higher complexity than the O(1), thus, it should run fewer times than
-instcombine pass.
