Chris Tate e3f02c73c9 Probe hashed number-key maps without normalizing integer keys

A number-key Map or Set read whose key has an integer view
(sc_map_entry_f64_int) fell back to the same hashed probe as any double
key, which tests for NaN and -0 before hashing. The fallback is now
sc_map_entry_f64_hashed_int, which takes the integer and converts it to
the key word directly: an integer is never NaN, and zero converts to +0.

Both hashed probes test the absent-key filter only before scanning a map
that keeps no bucket table. The filter keeps two of its 64 bits per key,
so it rejects few absent keys once a map has a bucket table, and the
probe's first bucket read answers those.

The map layout and the runtime lookup are unchanged. Corpus 8331 covers
integers the compiler tracks as integers on hashed maps and absent keys on
small bucket tables, and matches Node's output.
