Drop the target-specific trampolines for the standard slow path.
This lets us use tcg_out_helper_{ld,st}_args, and handles the new
atomicity bits within MemOp.
At the same time, use the full load/store helpers for user-only mode.
Drop inline unaligned access support for user-only mode, as it does
not handle atomicity.
Use TCG_REG_T[1-3] in the tlb lookup, instead of TCG_REG_O[0-2].
This allows the constraints to be simplified.
