87c977a52b Rename getMaximumUnrollFactor -> getMaxInterleaveFactor; also rename option names controlling this variable. 
"Unroll" is not the appropriate name for this variable. Clang already uses 
the term "interleave" in pragmas and metadata for this.

087ab613f4 Correct word hyphenations 
This patch tries to avoid unrelated changes other than fixing a few
hyphen-related ambiguities and contractions in nearby lines.

39f4e8d9cc Update Transforms tests to use CHECK-LABEL for easier debugging. No functionality change. 
This update was done with the following bash script:

  find test/Transforms -name "*.ll" | \
  while read NAME; do
    echo "$NAME"
    if ! grep -q "^; *RUN: *llc" $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
      mv $TEMP $NAME
    fi
  done

3c90b3d5fd Remove the -licm pass from the loop vectorizer test because the loop vectorizer does it now.

f7737b5baa Force a fixed unroll count on the target independent tests. 
This should fix clang-native-arm-cortex-a9. Thanks Renato.

bf8772ed2c Vectorize: teach cavVectorizeMemory to distinguish between A[i]+=x and A[B[i]]+=x. 
If the pointer is consecutive then it is safe to read and write. If the pointer is non-loop-consecutive then
it is unsafe to vectorize it because we may hit an ordering issue.

5dbe64e2bc Vectorizer: Add support for loop reductions. 
For example:

  for (i=0; i<n; i++)
   sum += A[i] +  B[i] + i;
