[binutils][2.25][objdump][ARM][PATCH 2/2] Backport Tests for 26-bit versions of teq, tst, cmn, cmp

[Andre Vieira <Andre dot SimoesDiasVieira at arm dot com>]

In the previous series patch the testsuite is updated to test the 
teq,tst,cmn and cmp instructions for later versions of the architecture. 
However, the 'legacy' 26-bit versions of teq, test, cmn and cmp can 
still be disassembled for armv5 and older. These tests were added to 
make sure we keep testing this functionality and don't loose it without 
going unnoticed.

This patch backports the fix from trunk to the binutils 2.25 branch.

The original patch is at:
https://sourceware.org/ml/binutils/2015-10/msg00166.html
