We were missing test cases for i16, i64, and f64. It's not super
critical, but it's also an easy addition, and helps bring coverage of
memory-tracing.cc up (close to 100% now).

Add kWasmS128 to the list of supported types, and implement Fill for all
the architectures so that LocalGet works.
Add a new test file to contain tests that run only on Liftoff, and
assert that the code is indeed compiled by Liftoff.
We cannot rely on the nooptimization variant for testing
because by default, if Liftoff compilation fails, it will fall back to
Turbofan, and we accidentally get a test passing.
We skip these tests on mips architecture that don't support SIMD, since
there is no way to implement these, and we don't have a "lowering" phase
for Liftoff.
As we implement more of SIMD in Liftoff, we can add more
tests to this file and ensure correctness. Future patches will introduce
support for globals and params.

Increase the embedded vector size to 91 as that is the max size needed to print
a s128 as a 32x4.
- max value of uint32_t has 10 digits in decimal, 1 for a potential sign,
3 spaces in between 4 of them -> 3 + 4 * 11 = 47
- max value of uint32_t has 8 digits in hex, 3 spaces in between -> 3 + 4 * 8 = 35
- the prefix "v128:" -> 5
- " / " to separate the decimal and hex representation -> 3
- null byte
47 + 35 + 5 + 3 + 1 = 91

For memory tracing, output a 'T' for Turbofan code and an 'L' for
Liftoff code. To do this, the WasmCodeWrapper now has some dispatch
functions which work for both on-the-heap and off-the-heap code.
We can probably refactor more code by having this mechanism.
Since the output of --wasm-trace-memory differs now between Turbofan
and Liftoff, the message test is split in two.
