Reuse HUseListNode<>s when replacing instruction or input.
Compiling the Nexus 5 boot image with the 64-bit dex2oat
on host this CL reduces the memory used for compiling the
most hungry method, BatteryStats.dumpLocked(), by ~5.6MiB:
Before:
MEM: used: 44393040, allocated: 45361248, lost: 968208
Number of arenas allocated: 319,
Number of allocations: 815492, avg size: 54
...
UseListNode 10308480
...
After:
MEM: used: 38554536, allocated: 39463008, lost: 908472
Number of arenas allocated: 274,
Number of allocations: 572221, avg size: 67
...
UseListNode 4469976
...
With 32-bit dex2oat, the UseListNode would be 2/3 of the
values for 64-bit dex2oat (both before and after).
