Replay jsval entry thunks in chunked emission and rename the profile's ABI marker

Chunked emission replays every numbered helper a range creates on the
merging emitter. The jsval entry thunks (dyn.jsEntryThunk) were missing
from the replayed dyn helpers, so a range that boxed a closure with a
jsval body failed to merge.

The committed runtime profile named the runtime ABI marker
scr_runtime_abi_v47, which ABI 48 renames to scr_runtime_abi_v48. The
profile's record now carries the new name; its hash and counts are
unchanged.
