copies: avoid unnecessary copying of copy dict When storing copy information in the changesets, this patch speeds up hg debugpathcopies FENNEC_58_0_2_BUILD1 FIREFOX_59_0b8_BUILD2 from 11s to 5.9s. That command takes 6.2s when storing copy information in filelogs. Differential Revision: https://phab.mercurial-scm.org/D6421
