Matt Arsenault 0b382a7cb8 DAG: Avoid OOB when legalizing vector indexing 
If a vector index is out of bounds, the result is supposed to be
undefined but is not undefined behavior. Change the legalization
for indexing the vector on the stack so that an out of bounds
index does not create an out of bounds memory access.

Rafael Espindola ae6000e86d Replace more uses of sse41 with sse4.1. 
llc using the host cpu features and *waning* on unknown features is probably
not a good thing :-(
