This commit fixes assertEquals, assertThrows/assertDoesNotThrow in
compatibility shim - we were failing some tests purely because of a
bad shim.
Two test files are moved from XFAIL_TESTS to SKIP_FILES:
1. es6/regexp-tostring.js: checks for V8-specific error message wording
2. es6/unicode-regexp-ignore-case-noi18n.js: tests V8's non-i18n build
behavior, it doesn't case-fold non-ASCII characters, but we do it
correctly.
The regexp-unicode-sets.js test is now included and passes.
All files that were previously in XFAIL_TESTS and SKIP_TESTS are now
passing, so both lists are cleared.
