Follows https://chromium-review.googlesource.com/c/374019/. Causes MinidumpMemoryListWriter to merge all overlapping ranges before writing the MINIDUMP_MEMORY_LIST. This is: 1) Necessary for the Google internal crash processor, which in some cases attempts to read the raw memory (displaying ASAN red zones), and aborts if there are any overlapping ranges in the minidump on load; 2) Necessary for new-ish versions of windbg (see bug 216 below). It is believed that this is a change in behavior in the tool that made dumps with overlapping ranges unreadable; 3) More efficient. The .dmp for crashy_program goes from 306K to 140K with this enabled. In Chrome minidumps where set_gather_indirectly_referenced_memory() is used (in practice this means Chrome Windows Beta, Dev, and Canary), the savings are expected to be substantial.
