Optimizing: Run gtests without creating the Runtime.
The only Optimizing test that actually needs a Runtime is
the ReferenceTypePropagationTest, so we make it subclass
CommonCompilerTest explicitly and change OptimizingUnitTest
to subclass CommonArtTest for the other tests.
On host, each test that initializes the Runtime takes ~220ms
more than without initializing the Runtime. For example, the
ConstantFoldingTest that has 10 individual tests previously
took over 2.2s to run but without the Runtime initialization
it takes around 3-5ms. On target, running 32-bit gtests on
taimen with run-gtests.sh (single-threaded) goes from
~28m47s to ~26m13s, a reduction of ~9%.
Test: m test-art-host-gtest
Test: run-gtests.sh
