These three functions are the only reason we need libandroid_support
post-L. Add these so we can remove it entirely for LP64 or users
targeting L+.
Test: make checkbuild
Test: build/soong/scripts/build-ndk-prebuilts.sh
Test: Imported the prebuilts generated from the above to the NDK,
`./checkbuild.py && ./run_tests.py` with a handful of patches
to remove libandroid_support for L+.
