Known-pointer decompression used to be distinct from any-tagged-value decompression, since the latter used to detect Smis and decompress them with sign extension. However, we got rid of this distinction when we introduced Smi-corrupting loads (allowing the top 32-bits of uncompressed Smis to be undefined), which means that the TaggedPointer and TaggedAny decompression is now identical. We can remove a bunch of duplicate code by removing this distinction.

V8 debug helper
This library is for debugging V8 itself, not debugging JavaScript running within V8. It is designed to be called from a debugger extension running within a native debugger such as WinDbg or LLDB. It can be used on live processes or crash dumps, and cannot assume that all memory is available in a dump.
