indirectCallTransformer takes a block (currBlock) and then expands it into a control flow. Typically, it ends up clonning various trees and insert some of them into the newly created blocks. We have to conservatively propagate various "has GT_ARR_LEN" bb flags for those to satify debug-only asserts in early-prop.
