Add -fmem-report-wpa
For parallel LTO builds setting -fmem-report does not work very well
because all the LTRANS phases dump it in parallel and typically interleave
it to unreadability.
Since usually the memory bottleneck is WPA add a flag to only dump
the memory report for that.

* gcc/lto/lto.c (do_whole_program_analysis): Run mem_report
when mem_report_wpa is set.
