19a6964088 m68k: add subregisters. on 68k, these are not as universal as on x86 and work differently, but the compiler needs this infrastructure to do 16bit math (which is a massive improvement on '000) or word-size indexes on CPUs which support it

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.

8b9e90dc7a * keep track of whether a routine has a C-style variadic parameter in the 
procoptions even when it's through an array-of-const parameter
  * always call create_varargs_paraloc_info() instead of create_paraloc_info()
    in the former case, even when no varargs parameters are specified (because
    on some platforms even some non-variadic parameters need to be passed
    differently, such as on ARM with gnueabihf)

122d0d36d6 + volatile() expression that marks an expression as volatile 
* disable matching volatile references in the assembler optimisers, so they
    can't be removed (more conservative than needed, but better than removing
    too many)
   o the CSE optimiser will ignore them by default, because they're an unknown
     inline node for it
  * also removed no longer used fpc_in_move_x and fpc_in_fillchar_x inline node
    identifiers from rtl/inc/innr.inc, and placed fpc_in_unaligned_x at the
    right place

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)

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now
