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

as well as insert_regalloc_info_all()
+ "register" allocator for the jvm target, which simply replaces every
virtual register with a temp. This is done for all register types in
one pass, so that the temps can be easily reused without worrying
about conflicts. Small optimisation: alloc/store/dealloc/load
sequences for a single reg are removed (many of these are generated
because most cg nodes return their value in a register which is then
immediately consumed by the parent)
* map addressregisters to integer registers with size R_SUBD, because
they require one stackslot (the subregister type is used by rgcpu
to determine the size of the temp it has to allocate)
