+ cghlcpu unit with thlbasecgcpu class that overrides all abstract tcg

    methods that don't have to be implemented by targets using the high
    level code generator, with dummy implementations that raise an internal
    error (to remove warnings about instantiating classes with abstract
    methods)
  * let the JVM tcg descendent derive from this new thlbasecgcpu class
