ART: Improve Constructor.newInstance
Special-case InvokeMethod to be constructor-specific so as to avoid
unnecessary and duplicate checks. Refactor for some code sharing.
Reduces Constructor.newInstance for Integer by approximately 15%
(ten runs of 10000000 invocations, reporting mean per invocation,
host x86-64 optimizing, perf stat numbers are for complete run
and do not exclude, for example, setup and prologue GC):
