Ng Zhi An d9381fd697 [wasm-simd][arm] Prototype f32x4.ceil
Prototype f32x4.ceil on ARM for both ARM v7 and ARM v8. ARM v8 has
support for vrintp, and for ARM v7 we fallback to runtime.

Since ARM v8 uses vrintp, which is the same instruction used for F32
Ceil (scalar), wasm-compiler reuses the Float32Round check, rather than
creating new F32x4Round optional operators.

Implementation for vrintp (Advanced SIMD version that takes Q
registers), assembler, disassembler support. Incomplete for now, but
more will be added as we add other rounding modes.
