Some systems have constrained rlimits for core files (the CrOS chroot is
an example of this). Fail gracefully in this case, rather than breaking

Evaluating CFI rules may fail due to e.g. the unavailability of the

than CFA or return address can be ignored because they are optional.

https://crrev.com/c/3327644 introduced the ability for dump_syms to
operate on in memory data, which has the consequence of not going
through the same input validation as the dump_syms cli tool. In certain
cases, it is possible that architecture info can't be reliably
determined, e.g. new architectures that breakpad is unware of. In that
case, dump_syms should avoid crashing when calling ReadSymbolData and
return false instead.
