Implements https://github.com/ARM-software/acle/pull/404 This allows the user to specify "featA+featB;priority=[1-255]" where priority=255 means highest priority. If the explicit priority string is omitted then the priority of "featA+featB" is implied, which is lower than priority=1. Internally this gets expanded using special FMV features P0 ... P7 which can encode up to 256-1 priority levels (excluding all zeros). Those do not have corresponding detection bit at pos FEAT_#enum so I made this field optional in FMVInfo. Also they don't affect the codegen or name mangling of versioned functions.
