Use ScopedArenaAllocator for code generation.
Reuse the memory previously allocated on the ArenaStack by
optimization passes.
This CL handles only the architecture-independent codegen
and slow paths, architecture-dependent codegen allocations
shall be moved to the ScopedArenaAllocator in a follow-up.
Memory needed to compile the two most expensive methods for
aosp_angler-userdebug boot image:
BatteryStats.dumpCheckinLocked() : 19.6MiB -> 18.5MiB (-1189KiB)
BatteryStats.dumpLocked(): 39.3MiB -> 37.0MiB (-2379KiB)
Also move definitions of functions that use bit_vector-inl.h
from bit_vector.h also to bit_vector-inl.h .
