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.

Without the section headers for the symbol table, there's no direct way
to calculate the number of entries in the table.
DT_HASH and DT_GNU_HASH are auxiliary tables that are designed to make
symbol lookup faster. DT_HASH is the original and is theoretically
mandatory. DT_GNU_HASH is the new-and-improved, but is more complex.
In practice, however, an Android build (at least vs. API 16) has only
DT_HASH, and not DT_GNU_HASH, and a Fuchsia build has only DT_GNU_HASH
but not DT_HASH. So, both are tried.
This change does not actually use the data in these tables to improve
the speed of symbol lookup, but instead only uses them to correctly
terminate the linear search.
DT_HASH contains the total number of symbols in the symbol table fairly
directly because there is an entry for each symbol table entry in the
hash table, so the number is the same.
DT_GNU_HASH regrettably does not. Instead, it's necessary to walk the
buckets and chain structure to find the largest entry.
DT_GNU_HASH doesn't appear in any "real" documentation that I'm aware
of, other than the binutils code (at least as far as I know). Some
more-and-less-useful references:
