…me lowering

SME instructions can only be used in streaming mode. PTRUE for
predicated counter and the ld/st pair can be used when:
  sve2.1  is available or
  sme2 available in function in streaming mode.
Previously the frame lowering only checking if sme2 available when
building the machine instruction.
This fix checks if sme2 is available and is subtarget in streaming mode
