compat.re2

// Behavioral test for compat.re2.
//
// Exercises the parts of RE2 that gRPC's xds matchers actually use — full and
// partial match with captures, a pre-compiled RE2 object, replacement, and the
// RE2::Set multi-pattern API — so a package that compiled but linked nothing
// useful cannot pass:
//
//   RE2 ctor / FullMatch / PartialMatch  -> re2/re2.cc, parse.cc, compile.cc, prog.cc
//   captures + rewriting                 -> re2/re2.cc, regexp.cc, simplify.cc
//   RE2::Set                             -> re2/set.cc, dfa.cc, nfa.cc
//   invalid pattern reporting            -> re2/parse.cc, tostring.cc
//   UTF-8 handling                       -> util/rune.cc, unicode_groups.cc
//
// Returns non-zero on any mismatch.
