ece8b73eb2 Use RegisterTuples to generate pseudo-registers. 
The QQ and QQQQ registers are not 'real', they are pseudo-registers used
to model some vld and vst instructions.

This makes the call clobber lists longer, but I intend to get rid of
those soon.

12216172c0 Make X86 instruction selection use 256-bit VPXOR for build_vector of all ones if AVX2 is enabled. This gives the ExeDepsFix pass a chance to choose FP vs int as appropriate. Also use v8i32 as the type for getZeroVector if AVX2 is enabled. This is consistent with SSE2 using prefering v4i32.

8dd6f0c835 Delete CodeInit and CodeRecTy from TableGen. 
The code type was always identical to a string anyway. Now it is simply
a synonym. The code literal syntax [{...}] is still valid.

c4b527ac06 DAGCombine's logic for forming pre- and post- indexed loads / stores were being 
overly conservative. It was concerned about cases where it would prohibit
folding simple [r, c] addressing modes. e.g.
  ldr r0, [r2]
  ldr r1, [r2, #4]
=>
  ldr r0, [r2], #4
  ldr r1, [r2]
Change the logic to look for such cases which allows it to form indexed memory
ops more aggressively.

805e2247fc A DenseMap of a std::map isn't a very good idea because the "grow()" method will 
need to make a deep copy of each of the std::maps. Use a std::map of the
std::map instead. This improves the compile time of sqlite3 by ~2%.
