Check invocation's side effects for LSE.
More optimization is allowed if an invocation doesn't do read/write.
Test: run-test on host.

Simplify handling of finalizable in LSE.
Finalizable is treated as being returned which simplifies its handling.
Test: run-test on host, 530-checker-lse contains tests on finalizable.

Optimizations around escape analysis. With tests.
Details:
(1) added new intrinsics
(2) implemented optimizations
more !can be null information
more null check removals
replace return-this uses with incoming parameter
remove dead StringBuffer/Builder calls (with escape analysis)
(3) Fixed exposed bug in CanBeMoved()
Performance gain:
This improves CafeineString by about 360%
(removes null check from first loop, eliminates second loop completely)
Test: test-art-host

Moved escape analysis to reusable module
Rationale:
This prepares other optimizations that
want to do some simple escape analysis.
Also introduces ability for client
to inject a case-specific function.
Test: test-art-host
