Add mcpu to tests to prevent them from using AVX instructions on Sandy Bridge after r155618. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155696 91177308-0d34-0410-b5e6-96231b3b80d8

Optimize splat of a scalar load into a shuffle of a vector load when it's legal. e.g. vector_shuffle (scalar_to_vector (i32 load (ptr + 4))), undef, <0, 0, 0, 0> => vector_shuffle (v4i32 load ptr), undef, <1, 1, 1, 1> iff ptr is 16-byte aligned (or can be made into 16-byte aligned). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90984 91177308-0d34-0410-b5e6-96231b3b80d8

entry:
Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally. This update was done with the following bash script: find test/CodeGen -name "*.ll" | \ while read NAME; do echo "$NAME" if ! grep -q "^; *RUN: *llc.*debug" $NAME; then TEMP=`mktemp -t temp` cp $NAME $TEMP sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \ while read FUNC; do sed -i '' "s/;\(.*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC: *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP done sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP mv $TEMP $NAME fi done git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186280 91177308-0d34-0410-b5e6-96231b3b80d8
