[PATCH] D36742: [LLD][ELF][AArch64] Implement scanner for Cortex-A53 Erratum 843419

Updated and rebased after addition of range-extension thunks for aarch64.

- The erratum scanning is now done within the same loop as range extension thunks.
- Added a new test case of an erratum sequence that will only be detected on the second pass. As the scanner only detects patches and doesn't try and fix them we cannot test the case where a new thunk is required due to a patch being added.
