gecko-dev/toolkit/moz.configure
Cameron McCormack a1e18da1b1 Bug 1573090 - Part 2: Look up ELF symbol tables directly when pre-symbolicating Gecko profiles on Linux. r=gerald
Whereas previously MozDescribeCodeAddress would have handled demangling,
we need to explicitly do that from our new GetFunction method.  The string we
generate is now more useful for the profiler to merge -- having dropped the
address in the previous patch, and the file & line number and library in this
patch.

While we're at it, try to demangle Rust symbols too.

Ideally we'd add Rust symbol handling to DemangleSymbol in
StackWalk.cpp, but that lives in mozglue, which currently cannot have
any Rust crate dependencies.
