Inline unimplemented intrinsics

There are intrinsics that are unimplemented i.e. we didn't
hand-craft code for them. Allow the inliner to inline those.

Since our optimizations expect InvokeVirtual, I stopped the
de-virtualization of intrinsics. That could be re-added
if we modify optimizations like TryReplaceStringBuilderAppend.

Test: art/test/testrunner/testrunner.py --host --64 --optimizing -b
Test: art/test/testrunner/testrunner.py --target --64 --optimizing
Test: compiling the APK in the bug and seeing the inline
