This change gets all of the section address ranges with executable permissions and registers these valid .text ranges with the verifier. This allows the verifier to ignore any address ranges that should have been stripped so they don't cause false overlapping errors. This is meant as a starting point to a solution for https://bugs.llvm.org/show_bug.cgi?id=46453. Hopefully we can discuss the pros and cons of this approach and see if this approach is worth persuing.
