JDK-8317683 - Add JIT memory statistics
Description
Compiler memory statistics, introduced with JDK-8317683, keeps a record of memory usage by C1 and C2. Records are kept per method for the most recent compilation.

It would make more sense to keep records on a per-compiler and per-method basis, though, to prevent recompilations from overwriting the other compiler's memory statistics.
