cse: Size insn_hash_table more realistically, speeding up CSE significantly
Profiling showed that Sparse spent much of its time doing CSE, which involved
traversing every bucket of insn_hash_table repeatedly. insn_hash_table had
64K buckets, but never more than a few dozen entries. Shrink insn_hash_table
to 256 entries. This makes Sparse 2-4 times faster for me.
