504f73f7b3 trace: add mmu_index to mem_info 
We are going to re-use mem_info later for plugins and will need to
track the mmu_idx for softmmu code.

291987c306 trace: expand mem_info:size_shift to 4 bits 
This will allow us to trace 32k-long memory accesses (although our
maximum is something like 256 bytes at the moment).

14776ab5a1 tcg: TCGMemOp is now accelerator independent MemOp 
Preparation for collapsing the two byte swaps, adjust_endianness and
handle_bswap, along the I/O path.

Target dependant attributes are conditionalized upon NEED_CPU_H.

3d69b95e5e trace: simplify trace_mem functions 
Add some defines for the mem_info bits, simplify
trace_mem_build_info, and also simplify trace_mem_get_info
by making it a wrapper around trace_mem_build_info.

This paves the way for increasing size_shift by one bit.

The event is described in "trace-events". Note that the "MO_AMASK" flag
is not traced, since it does not seem to affect the visible semantics of
