Bruno Cardoso Lopes 54366cc332 Add memory version of SHUFPD to mask decoding!

Bruno Cardoso Lopes f15dfe5818 The VPERM2F128 is a AVX instruction which permutes between two 256-bit 
vectors. It operates on 128-bit elements instead of regular scalar
types. Recognize shuffles that are suitable for VPERM2F128 and teach
the x86 legalizer how to handle them.

Duncan Sands 00f39c1521 Add obviously missing "break". Noticed by Andrey Karpov with 
the PVS-studio tool.

Bruno Cardoso Lopes b878caa5e2 Add support for 256-bit versions of VPERMIL instruction. This is a new 
instruction introduced in AVX, which can operate on 128 and 256-bit vectors.
It considers a 256-bit vector as two independent 128-bit lanes. It can permute
any 32 or 64 elements inside a lane, and restricts the second lane to
have the same permutation of the first one. With the improved splat support
introduced early today, adding codegen for this instruction enable more
efficient 256-bit code:

Instead of:
  vextractf128  $0, %ymm0, %xmm0
  punpcklbw %xmm0, %xmm0
  punpckhbw %xmm0, %xmm0
  vinsertf128 $0, %xmm0, %ymm0, %ymm1
  vinsertf128 $1, %xmm0, %ymm1, %ymm0
  vextractf128  $1, %ymm0, %xmm1
  shufps  $1, %xmm1, %xmm1
  movss %xmm1, 28(%rsp)
  movss %xmm1, 24(%rsp)
  movss %xmm1, 20(%rsp)
  movss %xmm1, 16(%rsp)
  vextractf128  $0, %ymm0, %xmm0
  shufps  $1, %xmm0, %xmm0
  movss %xmm0, 12(%rsp)
  movss %xmm0, 8(%rsp)
  movss %xmm0, 4(%rsp)
  movss %xmm0, (%rsp)
  vmovaps (%rsp), %ymm0
We get:
  vextractf128  $0, %ymm0, %xmm0
  punpcklbw %xmm0, %xmm0
  punpckhbw %xmm0, %xmm0
  vinsertf128 $0, %xmm0, %ymm0, %ymm1
  vinsertf128 $1, %xmm0, %ymm1, %ymm0
  vpermilps $85, %ymm0, %ymm0

David Greene 20a1cbefad [AVX] Add decode support for VUNPCKLPS/D instructions, both 128-bit 
and 256-bit forms.  Because the number of elements in a vector
      does not determine the vector type (4 elements could be v4f32 or
      v4f64), pass the full type of the vector to decode routines.

David Greene 3a2b508e8f [AVX] Recorganize X86ShuffleDecode into its own library 
(LLVMX86Utils.a) to break cyclic library dependencies between
LLVMX86CodeGen.a and LLVMX86AsmParser.a.  Previously this code was in
a header file and marked static but AVX requires some additional
functionality here that won't be used by all clients.  Since including
unused static functions causes a gcc compiler warning, keeping it as a
header would break builds that use -Werror.  Putting this in its own
library solves both problems at once.

Jim Grosbach 0e854f3d43 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.
