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: 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....

tcg-sparc: Implement brcond2.

Split out tcg_out_cmp and properly handle immediate arguments.
Fix constraints on brcond to match what SUBCC accepts.
Add tcg_out_brcond2_i32 for 32-bit host.

tcg-sparc: Use TCG_TARGET_REG_BITS in conditional compilation.

The test TCG_TARGET_REG_BITS==64 is exactly the feature that we
are checking for, whereas something involving sparc_v9 or
sparc_v8plus should be reserved for something ISA related,
as with SMULX....

tcg-sparc: Improve tcg_out_movi for sparc64.

Generate sign-extended 32-bit constants with SETHI+XOR.
Otherwise tidy the routine to avoid the need for
conditional compilation and code duplication with movi_imm32.

tcg-sparc: Fix imm13 check in movi.

We were unnecessarily restricting imm13 constants to 12 bits.
