[WebAssembly] Use "signed char" instead of "char" in SIMD intrinsics.
This allows people to use `int8_t` instead of `char`, -funsigned-char, and generally decouples SIMD from the specialness of `char`. And it makes intrinsics like `__builtin_wasm_add_saturate_s_i8x16` and `__builtin_wasm_add_saturate_u_i8x16` use signed and unsigned element types, respectively.
