8294186: AArch64: VectorMaskToLong failed on SVE2 machine with -XX:UseSVE=1

[e1iu]

C2_MacroAssembler::sve_vmask_tolong would fail on BITPERM supported SVE2 machine with "-XX:UseSVE=1".

BITPERM is an optional feature in SVE2. With this feature, VectorMaskToLong has a more efficent implementation. For other cases, it should generate SVE1 code.

[TEST] jdk/incubator/vector, hotspot/compiler/vectorapi passed on BITPERM supported SVE2 machine, with option -XX:UseSVE=(0, 1, 2).
