This CL implements a naive tiering-up strategy where the interpreter
is used for the first execution for every regex, and the compiler is
used for every execution after that. The only exception is if a
global replace is being executed on a regex, we eagerly tier-up to
native code right away.
To use the tier-up logic --regexp-tier-up needs to be set. It is
currently disabled by default.
