3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.

07bd4ba517 * let all the case code generation work with tconstexprint instead of aint, 
so it also works for 32 bit targets and a high level code generator
    (where aint is still 32 bit, but 64 bit operations are not decomposed)

4cd6f59bc3 * changed create_hlcodegen into a procvar, so that we don't have to insert 
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
   o prevents dependency cycles that can cause llvm codegen units to init
     before the cpu variants, which is bad since the llvm versions have to
     override the cpu variants in their init code (+ added checks in the
     init code that they are in fact initialised later)
