* x86 targets: Profiling shows that quite a bit of time is spent in findreg_by_number(), despite it uses binary search. Worse, it is repeated for every piece of register information. Trying to get rid of some of these calls: rearranged registers so that their "opcode" matches 3 LSBs of superregister number (with a few exceptions described at the beginning of x86reg.dat). This allows to lookup opcodes in regval() with O(1) complexity, and removes need in rXXXop.inc files.

* IF_SANDYBRIDGE designates CPU family, not feature. Mostly a cosmetic change, since we don't use these flags for anything.

* x86 assembler: write REX prefix before the first literal byte of instruction (this becomes possible once the instruction table has all $66,$F2,$F3 prefixes changed to non-literal control codes). This way it is no longer necessary to manually specify position of REX in every instruction entry (code \323 becomes obsolete), and the situation when REX is not written (IE 200603191) is hopefully gone forever.

* x86 assembler: operand type declarations rewritten using expressions instead of literal numbers where possible. Reassigned bit values to match the current NASM (the values themselves don't actually matter and can be chosen pretty arbitrary. What matters is the clean separation between different parts of the bitmask. In particular, the old value of XMM register class bit was equal to OT_BITS80, causing matching algorithm to effectively ignore it and accept e.g. MMX registers in place of XMM ones, part of Mantis #14387).
