Instead of pairing the reading of CleanSpec.mk files with the reading of Android.mk files, split them into separate, individually cachable steps. This way we only read Android.mk files once after a clean/sync. We'll still read the CleanSpec.mk files multiple times, but that's significantly faster than reading all the Android.mk files. This adds about 50ms if kati doesn't need to reread the CleanSpec.mk files. Reading all the CleanSpec.mk files takes about a second. Bug: 35970961 Test: m clean; m nothing; m nothing Test: Add CleanSpec.mk line, see it executed. Change-Id: I83bad15c50709510959d5b8b673a907b8aa7de82
