Ng Zhi An 9d1dda7e97 [wasm-simd][arm] Improve codegen for any_true 
The codegen uses a bunch of vpmax to try and keep set bits around. The
datatype for vpmax does not need to change for each instruction, since
vpmax U32 will persist set bits just as well. This simplifies the
instruction sequences for S1x8 and S1x16 anytrue.

I added a test to check a special case when a f64x2 contains -0.0 (top
bit set). A previous attempt to optimize codegen used floating point
compare, which does not distinguish between 0.0 and -0.0. So -0.0 will
compare equals to 0.0, and incorrect return 0 for anytrue.
