Spawned from https://phabricator.services.mozilla.com/D113269#3762061 and following comments, it seems possible to recover from some RtlLookupFunctionEntry() failures by trying to use the CONTEXT::Rbp register to find the caller's registers.

BP may contain the stack address where the caller's BP was pushed after the function call, in which case it's possible to carefully unwind from it.
This can get past JIT code, so there is no need to give up in this case.
