Reduce memory usage by other deps in scheduler.
Rely on transitive dependencies instead of adding the full
set of side effect dependencies.
Compiling a certain apk, the most memory hungry method has
the scheduler memory allocations in ArenaStack hidden by
the register allocator:
- before:
MEM: used: 155744672, allocated: 168446408, lost: 12036488
Scheduler 155744672
- after:
MEM: used: 5181680, allocated: 7096776, lost: 114752
SsaLiveness 4683440
RegAllocator 314312
RegAllocVldt 183928
The total arena memory used, including the ArenaAllocator
not listed above, goes from 167170024 to 16607032 (-90%).
(Measured with kArenaAllocatorCountAllocations=true,
kArenaAllocatorPreciseTracking=false.)
