Fix for a regression caused by the LoopVectorizer when vectorizing loops with memory accesses to non-zero address spaces. It simply dropped the AS info. Fixes PR16306. llvm-svn: 184103

; From a simple program with two address spaces:
; char Y[4*10000] __attribute__((address_space(1)));
; char X[4*10000];
; int main() {
; for (int i = 0; i < 4*10000; ++i)
; X[i] = Y[i] + 1;
; return 0;

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 llvm-svn: 186268
