use of the register (can happen if the register is unused afterwards;
remove the alloc/dealloc results in no temp being allocated for the
register, so that instruction becomes invalid)

and skip comments (so it works again when -ar is used, because
tlhcgjvm.inc/decstack() insert comments in that case)

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)
