7010913: JSR 292 ciMethodHandle does not handle MethodHandleCompiler exceptions properly
Reviewed-by:

This is a spin-off from 7009600 to fix the fact that
ciMethodHandle::get_adapter does not handle MethodHandleCompiler
exceptions properly.  7009600 should fix the actual conversion
problem.

ciMethodHandles::get_adapter should use CATCH instead of CHECK_NULL
which returns a null-pointer as target method.
