0fc1fd6ac1 * replaced current_procinfo.currtrue/falselabel with storing the true/false 
labels of LOC_JUMP in the node's location. This generates some extra jumps
    for short circuit boolean and/or-expressions if optimizations are off, but
    with optimisations enabled the generated code is the same (except for JVM
    because the jump threading optimisation isn't enabled there yet).

edd42aa42a * 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

5175a5ee07 * handle LOC_SUBSETREG,LOC_CSUBSETREG,LOC_SUBSETREF,LOC_CSUBSETREF in 
unaryminus code (a.o., fixes compiler crash with test/terecs6 on
    darwin/ppc32 under certain circumstances:

a23630260b + "weakexternal" support for imported procedures and variables. 
the syntax is exactly the same as for "external", except for
    the keyword. It is currently only active for Darwin targets.
    It should also work at least for Linux targets, but only with
    the GNU assembler (which is why it is not activated there)
  + test for this functionality

e815b923d5 * a_loadfpu_* gets two size parameters: fromsize and tosize 
* fixed downsizing the precision of floating point values
  * floating point constants are now treated using only the minimal
    precision required (e.g. 2.0 is now a single, 1.1 extended etc)
    (Delphi compatible)
