Antonio Sanchez ff4e7a0820 Add missing Packet2l/Packet2ul ops for NEON. 
The current multiply (`pmul`) and comparison operators (`pcmp_lt`,
`pcmp_le`, `pcmp_eq`) are missing for packets `Packet2l` and
`Packet2ul`. This leads to compile errors for the `packetmath.cpp` tests
in clang. Here we add and test the missing ops.

Tested:
```
$ aarch64-linux-gnu-g++ -static -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath
$ adb push packetmath /data/local/tmp/
$ adb shell "/data/local/tmp/packetmath"

$ arm-linux-gnueabihf-g++ -mfpu=neon -static -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath
$ adb push packetmath /data/local/tmp/
$ adb shell "/data/local/tmp/packetmath"

$ clang++ -target aarch64-linux-android21 -static -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath
$ adb push packetmath /data/local/tmp/
$ adb shell "/data/local/tmp/packetmath"

$ clang++ -target armv7-linux-android21 -static -mfpu=neon -I./ '-DEIGEN_TEST_PART_9=1' '-DEIGEN_TEST_PART_10=1' test/packetmath.cpp -o packetmath
$ adb push packetmath /data/local/tmp/
$ adb shell "/data/local/tmp/packetmath"
```
