Milad Farazmand 3fa75eca1b PPC/s390: Reland "[liftoff][wasm-simd] Implement f32x4.splat" 
Port b110d4808b

Original Commit Message:

    This relands commit 009993adb4.

    The fix is in liftoff-assembler-ia32.h, the codegen was incorrect.

    Original change's description:
    > Implement f32x4.splat and enable handling this in Liftoff.
    >
    > We add a new macro for defining test cases to run on TurboFan, Liftoff,
    > interpreter, and scalar lowering.
    >
    > Also add an assertion that the execution tier used is what we expected
    > it to be. This is useful for Liftoff, because by default it falls back
    > to TurboFan when it encounters an unimplemented opcode.
    >
    > Bug: v8:9909
