ART: Add regression test for obsolete crash.
Add a regression test for a `StringBuilderAppend` pattern
recognition crash in debug mode that we had while we were
inlining the `StringBuilder` constructor. As we no longer
inline this constructor, we do not encounter the bug.
Test: testrunner.py --target -t 639-checker-code-sinking
Test: Repeat on an older tree to see the crash - before
