Revert "Add a check in the location summary."
My assumption was wrong. We actually can use same as first input with any, *only if* the generate code does not clobber the first input. We use this for, e.g. DivZeroCheck, NullCheck. This reverts commit 95bf7547986e68d4ac93b0a529aaa8eb3c998c1f. Change-Id: Ib72d73fe580f5bc707b41c651f2c8936bd4e2407
