Pass memory statistics for {symbol,call}_summary.

Hi.

The pass passes memory allocation location to underlying
hash_map (and vec).

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin

gcc/ChangeLog:

2019-10-29  Martin Liska  <mliska@suse.cz>

	* symbol-summary.h (function_summary): Pass memory location
	to underlaying hash_map (or vec).
	(V>::fast_function_summary): Likewise.
