This contains the two missing checks for LC_SEGMENT load command fields. And checks for the Mach-O sections fields that would make them invalid. With the new checks, some of the existing malformed file checks now trips one of these instead of the issue it was having before so those tests were adjusted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@278557 91177308-0d34-0410-b5e6-96231b3b80d8

// These test checks that llvm-objdump will not crash with malformed Mach-O
|
|
// files. So the check line is not all that important but the bug fixes to
|
|
// make sure llvm-objdump is robust is what matters.
