Reland (again) "Enable the various chrome zlib optimizations."
This reverts commit 5ad12200f7f3fe49155385d787d67317799a90cf.
This time we enable the same optimizations on x86/x86-64 as on arm/arm64.
Optimized inflation is disabled because it breaks `atest
CtsLibcoreTestCases:org.apache.harmony.tests.java.util.zip.DeflaterTest`.
This version also distinguishes neon/non-neon builds because the NDK
builds a single libz. I don't trust -mfpu=neon not to cause all kinds of
neon dependencies; I don't think that our HWCAP tests would be
sufficient.
