x86: don't pretend that non-framepointer stack traces are reliable
Without frame pointers enabled, the x86 stack traces should not pretend to be reliable; instead they should just be what they are: unreliable. The effect of this is that they have a '?' printed in the stacktrace, to warn the reader that these entries are guesses rather than known based on more reliable information.
