Prepare compiler for adding VarHandle support.

This commit prepares the ground for adding VarHandle support
in the compiler. The intrinsic locations builder and code
generator are now triggered for HInvokePolymorphic nodes.
VarHandle and MethodHandle intrinsics are marked as unimplemented
rather than unreachable.

Since the Varhandle intrinsics are not implemented yet, the
functionality is not changed (i.e. the intrinsics are evaluated
at runtime and not compiled). I manually tested that the intrinsic
Visit* methods are triggered for the VarHandle methods.

Bug: b/65872996
Test: art/test.py --host -r -t 713-varhandle-invokers
Test: art/test.py --host --all-compiler -r
