Fix issue with Partial LSE and casts/instanceof

If PartialLSE encounters an instanceof or check-cast before the
escapes it could not correctly handle it. Due to how java language
code is typically developed and compiled this is generally not a
problem but could lead to incorrect codegen on release builds or
DCHECK failures on debug builds. This fixes the issues by (1) causing
partial LSE to consider check-cast and instance-ofs to be escaping.
This also updates the instruction simplifier to be much more
aggressive in removing instance-of and check-casts.
