tcg-sparc: Implement not.

The fallback implementation of "ret = arg1 ^ -1" isn't ideal
because of the extra tcg op to load the minus one.

tcg-sparc: Implement neg.

The fallback implementation of "ret = 0 - arg1" isn't ideal,
first because of the extra tcg op to load the zero, and second
because we fail to handle zero as %g0 for arg1 of the sub.

tcg-sparc: Implement ext32[su]_i64

The 32-bit right-shift instructions is defined to extend the shifted
output to 64-bits. A shift count of zero therefore is a simple
extension without actually shifting.

tcg-sparc: Implement division properly.

The {div,divu}2 opcodes are intended for systems for which the
division instruction produces both quotient and remainder. Sparc
is not such a system. Indeed, the remainder must be computed as

quot = a / b
rem = a - (quot * b)...

tcg-sparc: Do not remove %o012 from 'r' constraint.

Only 'L' constraint needs that.

tcg-sparc: Implement add2, sub2, mulu2.

Add missing 32-bit double-word support opcodes.

tcg-sparc: Add tcg_out_arithc.

Add a function to handle the register-vs-immediate test for arithmetic.

Also, adjust the OP_32_64 macro so that it auto-indents properly.
Rename the gen_arith32 label to gen_arith, since it handles 64-bit
arithmetic as well....
