* Reworked i386 division by constant optimization to reuse code from powerpc64. The algorithm is slightly different, signed version is one instruction shorter, unsigned one is one instruction longer (typically). The new algorithm is easily scalable for x86_64 target, unlike the old one.

* moved subsetref/reg and bit_set/test support from cgobj to hlcgobj for
...
future use by high level code generator targets
o this in turn required that all a_load*_loc* methods are called via
hlcg rather than via cg, since a location can be a subsetref/reg and
and those are no longer handled in tcg
o that then required moving several force_location_* routines into
thlcg because they use a_load_loc*, but did not take tdef size
parameters (which are required by the thlcg a_load_loc* routines)
o the only practical consequence is that from now on, you have to
use hlcg.location_force_mem/reg() (fpureg not yet) and
hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
might be involved
