Improve perf of select-keys by using keyword-identical?

Description

select-keys uses not= to compare keywords. Instead, using keyword-identical? results in decent speedups (an average of 1.34 across benchmarks and engines). Note that using identical? and lookup-sentinel doesn't appear to improve perf.
