This is where an LC_SEGMENT load command has a fileoff field that
extends past the end of the file.
Also fix llvm-nm and llvm-size to remove the errorToErrorCode() call so error messages are printed.
And needed to update a few test cases now that they do print the error messages just a
bit differently.

This reverts commit r259578.
There are enough issues with this small patch that it is better to
revert and then commit a fixed version (will be committed shortly).
