Evan Cheng f77b5ef3d0 Favors pshufd over shufps when shuffling elements from one vector. pshufd is faster than shufps.

Dan Gohman 54ec4bfa5f Change the x86 assembly output to use tab characters to separate the 
mnemonics from their operands instead of single spaces. This makes the
assembly output a little more consistent with various other compilers
(f.e. GCC), and slightly easier to read. Also, update the regression
tests accordingly.

Dan Gohman 60d6f96da3 Change the peep for EXTRACT_VECTOR_ELT of BUILD_PAIR to look for 
the new CONCAT_VECTORS node type instead, as that's what legalize
uses now. And add a peep for EXTRACT_VECTOR_ELT of INSERT_VECTOR_ELT.
