Kevin Enderby a7615b5302 Add the error handling for Mach-O dyld compact lazy bind, weak bind and ...

rebase entry errors and test cases for each of the error checks.

Also verified with Nick Kledzik that a BIND_OPCODE_SET_ADDEND_SLEB
opcode is legal in a lazy bind table, so code that had that as an error
check was removed.

With MachORebaseEntry and MachOBindEntry classes now returning
an llvm::Error in all cases for malformed input the variables Malformed
and logic to set use them is no longer needed and has been removed
from those classes.

Also in a few places, removed the redundant Done assignment to true
when also calling moveToEnd() as it does that assignment.

This only leaves the dyld compact export entries left to have
error handling yet to be added for the dyld compact info.
