Supersize: Create aliases for inline symbols 

If a symbol was found in multiple object files, we would previously have
changed its object path to be the common ancestor of all paths it
appeared in. This is a problem because it would cause queries based on
path to not find these symbols.

On the flip side, we were creating string literal aliases for every
path a string literal appeared in. For small strings such as "", or
"\n", this would lead to an unreasonable number of aliases.

This changes supersize to first create symbols for all paths, and then
collapse groups with a large number of aliases into a single symbol with
ancestor paths.

Before this change:
.text: 48998 symbols have shared ownership (1553806 bytes)
.rodata: 541 symbols have shared ownership (285728 bytes)

After:
.text: 1586 symbols have shared ownership (48252 bytes)
.rodata: 141 symbols have shared ownership (2828 bytes)

This increases the symbol count 702115->912322 and the file size
9.67mb->10.39mb.

This increases the runtime on my machine from ~40s -> ~42s.

inline functions defined in `.h` files, and string literals that are de-duped

per path, but are sometimes collapsed into a single symbol where the path is
set to `{shared}/$SYMBOL_COUNT`. This collapsing is done only for symbols owned
by a large number of paths.
