c9f8703679 + set ref.segment to NR_SS for all temps/localvars on i8086. This allows the 
segment to survive e.g. several nested vecnodes, which cause the base register
  to change from BP to something else. In the cases where the ss: prefix is not
  needed, it is removed by make_simple_ref.

5af873ee5b * 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.

5d628b29bb * set the subregsize of OS_M64 SSE registers to R_SUBQ so we can 
differentiate between 64 bit and 128 bit (R_SUBMMWHOLE) SSE vector regs,
    and support spilling/assembling for R_SUBQ SSE registers (8 bytes)
    (mantis #23962)

    We currently never use the full 128 bit of an SSE register, and
    spilling for those hasn't been implemented yet either (R_SUBMMWHOLE
    SSE regs are spilled into a 4-byte temp currently -> can overwrite data)

d908fb42f7 x86 assembler fixes: 
* Factored repeating REX operations into a separate function.
* Fixed instruction matching bug which was preventing compilation of 3-operand SIMD instructions with RIP-relative operand + test.
* Do not adjust offset of RIP-relative reference if it is a literal number, this was causing 0x123(%rip) to assemble as 0x122(%rip) in 3-operand instructions. Now tasm2.pp is the same with and without -Aas. Also fixed the expected result, improved verbosity of diagnostic and removed %norun, so it is actually executed.
+ Disallow high-byte registers in instructions requiring REX + test.

86d0c7f4c5 * 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.

6d0d8734e0 * 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). 
* Fixed matching of memory references with OT_XMMRM and OT_MMXRM.

de8ae0f873 x86 assembler improvements: 
* Simplified REX handling: instead of useless adjusting instruction length on every REX change, adjust it just once, based on the final REX value.
* Similar for omitting REX.W in certain instructions: set a flag and consider it once the entire instruction has been processed. This removes the requirement for \335 to be the last opcode.
* maybewriterex also after $F2 prefix
* Fixed behavior of codes \310 and \311 (16- and 32-bit address respectively), this is needed for a few fancy instructions like LOOP and JCXZ, which honor address-size prefix instead of REX.
+ control code \361 for $66 prefix
+ IF_SSSE3, IF_SSE41, IF_SSE42 instruction flags (with dummy values)

x86/x86ins.dat:
* replaced literal $67 prefixes with \310 or \311
* marked encodings containing code \310 as NOX86_64
* replaced literal $48 prefixes with \326

0da9d36116 * fixed internal assembler for x86-64 so that it correctly handles 
relocations for addr_pic_no_got references (do not go via the GOT)
  * fixed code generator so that it generates addr_pic_no_got references
    also for platforms that use the internal assembler (this will break linking
    of some tests that check static data > 2GB on Linux/x86-64, but they were
    already broken before as well because we don't use the "huge" x86-64
    execution model)

71202a141d * taicpu.is_same_reg_move() now gets a regtype parameter so it only 
removes moves of that particular register type. This is necessary so
    we don't remove the live_start instruction of a register before it
    has been processed

663fa583d9 * real fix for the short jmp out of range problem. Only forward jumps 
needs an offset correction. For backward jumps both the address of
    the symbol and the instruction are already updated so no correction
    is required.
