bc9deba8ad R600: Move CONST_ADDRESS folding into AMDGPUDAGToDAGISel::Select()
This increases the number of opportunites we have for folding.  With the
previous implementation we were unable to fold into any instructions
other than the first when multiple instructions were selected from a
single SDNode.

5399a0520e Add aliases to map 'imm, mem' form of x86 bts/btr/btc without a size suffix to their 32-bit forms.
This makes them consistent with 'bt' which already had this handling. gas has the same behavior. There have been discussions on the mailing list about determining size based on the immediate, but my goal here was just to remove the inconsistency.

f89dce68af Explicitly don't let the asm printer use the clrb/w/l aliases for xor %reg, %reg.
It only didn't use it before because it seems InstAlias handling in the asm printer fails to count tied operands so it tried to find an xor with 2 operands instead of the 3 it wfails to count tied.

383f980dca When we vectorize across multiple basic blocks we may vectorize PHINodes that create a cycle. We already break the cycle on phi-nodes, but arithmetic operations are still uplicated. This patch adds code that checks if the operation that we are vectorizing was vectorized during the visit of the operands and uses this value if it can.

1e13d52088 Initialize/Register LTO passes to enable flags like -print-after=<lto-pass>
There already have two "dead" functions, initialize{IPO|IPA}, defined for 
similar purpose. I decide not to call these two functions for two reasons:
  o. they don't cover all LTO passes (which will soon be separated into IPO 
     and post-IPO passes)
  o. We have not yet figured out the right passes and the ordering for IPO 
     and post-IPO stages, meaning this change is only for the time being.

Since LTO passes are registered, we are now able to print IR before and 
after particular point.

For OSX users:
--------------
  "...-Wl,-mllvm -Wl,-print-after=<pass-name>" will print IR after the
  specified pass.

For Other UNIX with GNU gold linker:
------------------------------------
  "-Wl,-plugin-opt=-print-after=<pass-name>" should work.
  (NOTE: no need for "-Wl,-mllvm")

  Strip "-Wl," if flags are fed directly to linker instead of clang/clang++.

ea82a920ae MC: mayAffectControlFlow() handling for variadic instructions.
Variadic MC instructions don't note whether the variable operands
are uses or defs, so mayAffectControlFlow() must conservatively
assume they are defs and return true if the PC is in the operand
list.

53033f1204 Fix an obvious typo in the loop vectorizer where the cost model uses the wrong variable. The variable BlockCost is ignored.
We don't have tests for the effect of if-conversion loops because it requires a big test (that includes if-converted loops) and it is difficult to find and balance a loop to do the right thing.

9cfbdad631 Replace archive members in the old position.
This matches gnu archive behavior and since archive member order can change
which member is used, not changing the order on replacement looks like the
right thing to do.

This patch also refactors the logic for which archive member to keep and
whether to move it to a helper function (computeInsertAction). The
nesting in computeNewArchiveMembers was getting a bit confusing.
