This required splitting wasm-run-utils.h in header and implementation,
since the anonymous namespace in wasm-run-utils.h is now gone.
This is a reasonable refactoring in itself.

This CL removes most occurences of "WASM" from outputs and comments in
the code. They are replaced either by "WebAssembly" or (especially in
comments) "wasm". These are the spellings officially proposed on

Most prototype implementations are not fully supported in the
interpreter. This is the case at least for exception handling, simd, and
atomics. Any function can be redirected to the interpreter though,
either by passing --wasm-interpret-all, or by dynamically redirecting to
the interpreter for debugging.
Making the flags experimental keeps the fuzzer from playing around with
these flags.
Drive-by: Refactor tests which explicitly set the prototype flag to use
a new scope for that.

Currently SIMD integer comparison ops are implemented using Lt/Le, this is
sub-optimal on Intel, because all compares are done using pcmpgt(d/w/b) that
clobber the destination register, and will need additional instructions to
when using Lt/Le as the base implementation. This CL proposes moving to Gt/Ge
as the underlying implementation as this will only require swapping operands
on MIPS and is consistent with x86/ARM instructions.

that take many cycles to complete.
- Remove F32x4RecipRefine, F32x4RecipSqrtRefine. Clients are better off
synthesizing these from splats, multiplies and adds.
- Remove F32x4Div, F32x4Sqrt, F32x4MinNum, F32x4MaxNum. Clients are
better off synthesizing these or using the reciprocal approximations,

- Adds WASM opcodes I32x4SConvertI16x8Low, I32x4SConvertI16x8High,
I32x4UConvertI16x8Low, I32x4UConvertI16x8High, which unpack half of
an I16x8 register into a whole I32x4 register, with signed or unsigned
extension. Having separate Low/High opcodes works around the difficulty
of having multiple output registers, which would be necessary if we unpacked
the entire I16x8 register.
- Adds WASM opcodes I16x8SConvertI8x16Low, I16x8SConvertI8x16High,
I16x8UConvertI8x16Low, I16x8UConvertI8x16High, similarly to above.
- Adds WASM opcodes I16x8SConvertI32x4, I16x8UConvertI32x4,
I8x16SConvert16x8, I8x16UConvertI16x8, which pack two source registers
into a single destination register with signed or unsigned saturation. These
could have been separated into half operations, but this is simpler to
implement with SSE, AVX, and is acceptable on ARM. It also avoids adding
operations that only modify half of their destination register.
- Implements these opcodes for ARM.
