[ARM] Convert some tests to opaque pointers (NFC)

[ARM] Replace arm_neon_vqadds with sadd_sat

This replaces the A32 NEON vqadds, vqaddu, vqsubs and vqsubu intrinsics
with the target independent sadd_sat, uadd_sat, ssub_sat and usub_sat.
This helps

This replaces the A32 NEON vqadds, vqaddu, vqsubs and vqsubu intrinsics
with the target independent sadd_sat, uadd_sat, ssub_sat and usub_sat.
This helps generate vqadds from standard IR nodes, which might be
produced from the vectoriser. The old variants are removed in the
process.

[opaque pointer type] Add textual IR support for explicit type parameter to load instruction

Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test

Essentially the same as the GEP change in r230786.

A similar migration script can be used to update test cases, though a few more
test case improvements/changes were required this time around: (r229269-r229278)

ARM: remove unused v(add|sub)hn and vqdml[as]l intrinsics.

Clang is now generating cleaner IR, so this removes the old variants which
should be completely unused.

ARM: add patterns for vqdmlal with separate vqdmull and vqadds

The vqdmlal and vqdmlls instructions are really just a fused pair consisting of
a vqdmull.sN and a vqadd.sN. This adds patterns to LLVM

ARM: add patterns for vqdmlal with separate vqdmull and vqadds

The vqdmlal and vqdmlls instructions are really just a fused pair consisting of
a vqdmull.sN and a vqadd.sN. This adds patterns to LLVM so that we can switch
Clang's CodeGen over to generating these instead of the special vqdmlal
intrinsics.

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

make the asmparser reject function and type redefinitions. 'Merging' hasn't been
needed since llvm-gcc 3.4 days.

Merge a bunch of NEON tests into larger files so they run faster.
