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.

63c1a05718 * SPARC: Removed hacks with g1_used that were used for g_intf_wrapper to be operational without initialized reg.allocator, and replaced them with a proper solution (which is basically a clone from MIPS cg).

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.

176d8434e4 * SPARC: completely rewrote PIC-related code, got it twice shorter in source lines and much less instructions in generated code. 
+ Enable registers %i0..%i5 and %o7 for use by reg.allocator.

Some notable properties of this implementation are:
  o pi_needs_got flag can be safely set during pass 2, so not setting it occasionally in pass 1 does not result in internal error.
  o Reg.allocator configuration is independent from PIC. If procedure requires GOT, register %l7 is allocated at the prologue, making it unavailable to RA.
  o GOT is stored in fixed %l7 register, but it is trivial to switch over to virtual register.

eaba90dda7 * SPARC: since peephole optimizer recognizes only one conditional branching instruction, generate all branches using A_Bxx opcode, and change it to A_FBxx if necessary when writing assembler. This enables optimization of floating-point branches. 
* Assembler reader: rewrote branch condition matching part, don't try to match integer suffixes to floating-point branches and vice versa.
