Fix a crash on some platforms where a dSYM for a system library lists a DW_AT_mips_linkage_name for
a non-mangled function - we pass the non mangled string down through abi::__cxa_demangle and it
crashes. Usually passing non mangled strings to abi::__cxa_demangle works out fine but not
always, apparently.
