[gas][arm] Enable VLDM, VSTM, VPUSH, VPOP for MVE
This patch enables a few instructions for Armv8.1-M MVE. Currently VLDM,
VSTM, VSTR, VLDR, VPUSH and VPOP are enabled only when the Armv8-M
Floating-point Extension is enabled. According to the ARMv8.1-M ARM,
section A.1.4.2[1], they can be enabled by having "Armv8-M Floating-point
Extension and/or Armv8.1-M MVE".
