The tick-processor expects a certain format for functions in d8's
cpu profile log (--prof). To make wasm functions look like js functions,
this change adds a fake address to the log output that can be used as
key for the wasm function. This enables basic profiling of wasm code
using the --prof flag and the tick-processor.
