Fix Regexp#to_s for GC compaction
The test fails when RGENGC_CHECK_MODE is turned on:
TestRegexp#test_to_s_under_gc_compact_stress = 13.46 s
1) Failure:
TestRegexp#test_to_s_under_gc_compact_stress [test/ruby/test_regexp.rb:81]:
<"(?-mix:abcd\u3042)"> expected but was
<"(?-mix:\u5C78\u3030\u5C78\u3030\u5C78\u3030\u5C78\u3030\u5C78\u3030)">.
