Commit Message

Pack and unroll the inflate_table replication store

The inner replication loop in zng_inflate_table writes the same `code`
struct to a strided sequence of root-table slots. The struct's three
fields ({bits, op, val}) compiled to three separate stores per slot
(strb+strb+strh on AArch64), and each iteration's address depended on
the previous fill value so the stores serialized.

Pack the struct into a uint32_t once before the loop so each slot takes
a single 4-byte store, and unroll the loop four ways so consecutive
stores have independent address calculations and can issue in parallel
on wide-out-of-order cores. Verified with gtest_zlib and infcover. About
1-5% faster on inflate_bench and inflate_chunked benchmarks; benefit
scales with the number of dynamic blocks and their table sizes.
