* refactored i8086's thlcgcpu.location_force_mem:
...
o The checks for types that need special handling moved to separate methods,
because they'll probably be used by the other hlcg.a_load*loc* methods as
well.
o Use voidcodepointertype and voidpointertype to avoid the ifs for checking
the memory model.

the high level code generator. All hlcg code, except for the jvm code
generator, updated to use the new method. I didn't update jvm (it still uses
the method from cgutils), because I'm not familiar with that platform, so I
might get the types wrong.

generator.
