libtimeinstate: change map format to improve performance By storing times for up to 32 freqs in each map value instead of one time per value, we can drastically reduce the number of syscalls required to get the data for a single UID and for all UIDs. This translates into a better than 3x speedup in getUidsCpuFreqTimes(). Test: libtimeinstate_test passes Bug: 138317993 Change-Id: I0d2d4d5fc99a82179a84a9aa83101bc55ddbc0e4 Signed-off-by: Connor O'Brien <connoro@google.com>
