Leszek Swirski 81aa89592b [ptrcomp] Remove the distinction of TaggedAny and TaggedPointer 
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.
