3cb9be73bc Moved tcontrollerdatatype out into cpuinfo. 
Added cputype and fputype info to tcontrollerdatatype arrays.

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).

b70c5efa65 * SPARC peephole: check that result of GetNextInstructionUsingReg is actually an instruction, because GetNextInstruction can stop at a label. Resolves #26798. 
The same issue on MIPS targets was fixed by r28380, but I forgot to apply it also to SPARC.

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

c673c32ad9 + SPARC: generate position-independent case jump tables, as specified by ABI.

720b9bf560 * SPARC: reworked 64-bit comparisons so their result is always in flags. Comparisons are emitted as subtractions, sides are optionally swapped to avoid using Z flag (since it is not set correctly in multi-word subtraction). This generates significantly shorter code: when both sides are in registers it is just 3 instructions for equal/unequal and 2 instructions otherwise.

05489d6e05 * SPARC: fixed g_intf_wrapper for non-virtual methods once again, my initial assumption was not correct: a wrapper does not necessarily reference methods from the class that implements the interface, it may be methods from parent classes, which can be located arbitrarily far away in address space. 
Now using code from g_external_wrapper, which has no distance limit and is only one instruction longer.
