tcg-i386: Use TCGMemOp within qemu_ldst routines

Step one in the transition, with constants passed down from tcg_out_op.

tcg-i386: Tidy softmmu routines

Pass two TCGReg to tcg_out_tlb_load, rather than idx+args.

Move ldst_optimization routines just below tcg_out_tlb_load to avoid
the need for forward declarations.

Use TCGReg enum in preference to int where apprpriate.

tcg-i386: Remove "cb" output restriction from qemu_st8 for i386

Once we form a combined qemu_st_i32 opcode, we won't be able to
have separate constraints based on size. This one is fairly easy
to work around, since eax is available as a scratch register....

tcg-i386: Support new ldst opcodes

No support for helpers with non-default endianness yet,
but good enough to test the opcodes.

tcg: Add qemu_ld_st_i32/64

Step two in the transition, adding the new ldst opcodes. Keep the old
opcodes around until all backends support the new opcodes.

tcg-i386: Make use of zero-extended memory helper routines

For 8 and 16-bit unsigned loads, rely on the zero-extension
from the helper and use a smaller 32-bit move insn.

tcg-i386: Don't perform GETPC adjustment in TCG code

Since we now perform it inside the helper, no need to do it here.
This also lets us perform a tail-call from the store slow path to
the helper.

exec: Split softmmu_defs.h

The _cmmu helpers can be moved to exec-all.h. The helpers that are
used from TCG will shortly need access to tcg_target_long so move
their declarations into tcg.h.

This requires minor include adjustments to all TCG backends.
