target/i386: reimplement 0x0f 0xd0-0xd7, 0xe0-0xe7, 0xf0-0xf7, add AVX

Browse source 
The more complicated ones here are d6-d7, e6-e7, f7.  The others
are trivial.

For LDDQU, using gen_load_sse directly might corrupt the register if
the second part of the load fails.  Therefore, add a custom X86_TYPE_WM
value; like X86_TYPE_W it does call gen_load(), but it also rejects a
value of 11 in the ModRM field like X86_TYPE_M.
