* support for compiling the objects unit methods that expect local procedure/

function pointers using {$modeswitch nestedprocvars} functionality, activate
    this for LLVM and also activate that modeswitch for a test that uses this
   o also convert the IDE units to use this functionality
   o requires extra typecasts because implicit type conversions from
     procvar(p: psometype) to procvar(p: pointer) are not supported; on the
     plus side, even those type conversions are checked for validity
   o note: requires {$modeswitch nestedprocvars} in all programs/units
     that rely on this functionality
