[PATCH] [AArch64] Customer lowering of CTPOP to SIMD should check for NEON availability

[Weiming Zhao]

Hi apazos,

When passing -mgeneral-regs-only, compiler crashes as it tries to lower CTPOP to "cnt v0.8b..." unless -mno-implicit-float presents.  But users may not aware the -mno-implicit-float flag and ICE is not good.
