Reduce Partial LSE memory usage.
Instantiate ExecutionSubgraph only for partial singleton
candidates (currently NewInstance, possibly NewArray in the
future). This reduces "LSA" allocations.
Reserve memory for PartialLoadStoreEliminationHelper members
based on the number of partial singletons instead of the
number of reference infos. This reduces "LSE" allocations.
The peak scoped arena allocation for one compiled method
is reduced from
MEM: used: 97424004, allocated: 99006568, lost: 1115968
LSA 46015104
LSE 51408900
down to
MEM: used: 17000744, allocated: 26713880, lost: 3332496
GVN 17000744
where the LSA+LSE memory use is lower than GVN use.
