5cd95e1478 When ext-loading and trunc-storing vectors to memory, on x86 32bit systems, allow loads/stores of 64bit values from xmm registers.

2dd83eb1ab Improve the loading of load-anyext vectors by allowing the codegen to load 
multiple scalars and insert them into a vector. Next, we shuffle the elements
into the correct places, as before.
Also fix a small dagcombine bug in SimplifyBinOpWithSameOpcodeHands, when the
migration of bitcasts happened too late in the SelectionDAG process.
