// Creates an OSR entrypoint that establishes all argument and local variable
// values. This entrypoint only works for the Plan::osrEntryBytecodeIndex.
// Unlike ordinary OSR entry into the DFG, this forces all variables slurped
// in through OSR entry to appear TOP to the CFA. Hence this phase must be run
// early - before doing any CFA. But this also does some additional hacks that
// require this to run before unification.
