[AArch64] Cortex-a53-843419 erratum should not apply to relaxed TLS.

The changes to the instructions performed by TLS relaxation and the errata
patching are performed with relocations. As these are applied so late the
errata scanning won't see the changes in the section data made by the TLS
relaxation. This can lead to a TLS relaxed sequence being patched when it
doesn't need to be.

The fix checks to see if there is a R_RELAX_TLS_IE_TO_LE instruction at the
same address as the ADRP as this indicates the presence of a relaxation
of a sequence that might get recognised as a patch.

Benchmarking

In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
