[JVMCI] check alignment of call displacement during code installation

      Description

        We have the following crash on GraalVM:

        # Internal Error (nativeInst_x86.cpp:155), pid=19, tid=0x00007f410b0f4700
        # guarantee(!os::is_MP() || is_aligned) failed: destination must be aligned

        This implies a problem in Graal in terms of emitting code that complies with HotSpot's code patching requirements. It would be preferable for the compilation to fail gracefully/silently than for the whole VM to stop. As such, JVMCI should verify these alignment invariants during code installation.
