In non-pie binaries BOLT unconditionally converted type encoding from indirect to absptr, which broke std exceptions since pointers to their typeinfo were only assigned at runtime in .data section. In this patch we preserve original encoding so that indirect remains indirect and can be resolved at runtime, and absolute remains absolute.
