Description
To create a FuzzManager signature for https://bugzilla.mozilla.org/show_bug.cgi?id=1288589 (as seen by minidump_stackwalk), I'd like to specify that the crash has to have AppleIntelHD3000GraphicsGLDriver on the stack so I can still find bugs on computers with other graphics cards. But currently, MinidumpCrashInfo just creates "??" entries when it doesn't have symbols for system libraries.
I guess library+offset would make signatures change too often, and some debuggers unhelpfully give library+address. So I'm suggesting using just the library name, as an improvement over using "??".

Research direction
Start by locating MinidumpCrashInfo and reviewing the linked gist for the missing-symbol behavior. Trace how stack entries are produced when system-library symbols are unavailable, then inspect the relevant existing tests. Done means those entries use the library filename instead of "??" without adding offsets or addresses.
