Commit Message

perf: share precompiled regexps for common component patterns (#12)

Compiling a URLPattern compiles one regexp per URL component. In typical
patterns most components are the full wildcard (the default for username,
password, search and hash) or empty (a common port), whose generated
expressions are a small fixed set of constant strings. Reuse a shared
precompiled *regexp.Regexp for those (safe for concurrent use) instead of
calling regexp.Compile per component.

New geomean: -21% time, -25% B/op, -22% allocs (BenchmarkNew).
