338c064beb * moved x86-specific tpointerdef functionality to architecture-specific 
descendants

4a79481c51 * isolated segment-related functionality of tabsolutevarsym into i386/i8086- 
specific descendent classes and moved the code that deals with this in the
    code generator also to target-specific classes -> only ifdefs left in
    pdecvar

b57c95043f + support overriding tdef/tsym methods with target-specific functionality: 
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

26b53607f8 + added method reference_reset_base with support for different pointer types to 
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.

c003f934c5 * Included cs_opt_peephole into genericlevel1optimizerswitches, so it is re-enabled for all targets after r27106. 
- Removed cs_opt_peephole from level1optimizerswicthes on i386 and i8086, it is redundant due to the above change.

2c02e8a726 - i386, x86_64, SPARC: removed paramanager.getintparaloc overrides, it is handled by generic implementation since r24716. 
(This probably can be removed for all targets, but I don't want to do it without prior testing).

179586f589 + SEH support for Win32. Enable by cycling with OPT=-dTEST_WIN32_SEH. 
Although basic things work (no regressions in test suite, also with TEST_OPT=-O2), there are some secondary issues/TODOs:
- Exception frame around PASCALMAIN is not properly removed in DLLs
- No stack traces yet
- Stack overallocated in finalizer procedures, their entry/exit code needs cleanup
- Signals unit is probably completely broken.
