This patch adds support for generating instruction samples from trace of AArch32 programs using the A32 and T32 instruction sets. T32 has variable 2 or 4 byte instruction size, so the conversion between addresses and instruction counts requires extra information from the trace decoder, requiring version 0.10.0 of OpenCSD. A check for the OpenCSD library version has been added to the feature check for OpenCSD.
