    [Liftoff] Add memory tracing support · 4dc85663
    Clemens Hammacher authored
    This adds support for tracing memory operations in code compiled with
    Liftoff. This is the first runtime call we emit from Liftoff code, so
    part of this code can be reused for other runtime calls.
    
    Drive-by: Reuse outer compilation zone (avoid one Zone allocation).
    
    Bug: v8:6600, v8:7210
