* Dummy implementations of a_bit_scan_reg_reg and g_stackpointer_alloc in tcg, removes the need to override these methods in every descendant code generator solely to avoid "constructing a class with abstract method" warning.

* SPARC: OP_NOT can always be done in 32 bits, because for 8 and 16-bit operations the high bits of result are adjusted immediately afterwards.

* SPARC: r26561 caused a_op_const_reg_reg used for zero-extending 8-bit values to be optimized away. Fixed by replacing it with an explicit instruction.

+ added a size parameter to optimize_op_const and do a sign extension of the 'a' parameter up from the specified size, so that things like (i and $ffffffff) get optimized away the same way as (i and -1)

* 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).

* 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.

* 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.

* SPARC: fixed PIC interface wrappers for non-virtual methods. The fix uses branching with 8 MB distance limit, but in particular case of interface wrappers this limit applies to code size of a single unit, not to entire program, and is therefore hard enough to reach.
