Remove 'break's to make sure we see all options.

Otherwise, zip-fd will make compiler-filter be ignored and vice-versa.
For example, we now get from OTA:
/system/bin/dex2oat --input-vdex-fd=14 --output-vdex-fd=14 --compiler-filter=verify -j4 --classpath-dir=/data/app/com.google.android.GoogleCamera-TPUvotvLcRVexUZ6bjX2pA== --compiler-filter=speed
