<pre>ARM has a number of architecture extensions. These can be enabled on a region
of the object file, changing the effective triple required for disassembly. We
should record these so that we can enable the appropriate target features when
disassembling an object file.
Because a file can have multiple functions each with a different set of
extensions enabled (useful for accelerated variants), we need to associate them
with a COMDAT with the function so that they can be encoded into the vendor
extension namespace of `.ARM.extensions`.</pre>
