[ptrcomp] Remove the distinction of TaggedAny and TaggedPointer

Browse Source 
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.
