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.

1. A list of symbols, including name, address, size,
padding (caused by alignment), and associated `.o` / `.cc` files.
#### How are Symbols Collected?
1. Symbol list is Extracted from linker `.map` file.
* Map files contain some unique pieces of information, such as
`** merge strings` entries, and the odd unnamed symbol (which map at least
lists a `.o` path).
* Map files contain some unique pieces of information compared to `nm` output,
such as `** merge strings` entries, and some unnamed symbols (which
although unnamed, contain the `.o` path).
1. `.o` files are mapped to `.cc` files by parsing `.ninja` files.
* This means that `.h` files are never listed as sources. No information about
inlined symbols is gathered.
......@@ -87,8 +86,15 @@ between milestones.
* Aliases are created by identical code folding (linker optimization).
* Aliases have the same address and size, but report their `.pss` as
`.size / .num_aliases`.
1. Paths for shared symbols (those found in multiple `.o` files) are collected
by running `nm` on every `.o` file.
1. `** merge strings` symbols are further broken down into individual string
literal symbols. This is done by reading string literals from `.o` files, and
then searching for them within the `** merge strings` sections.
1. "Shared symbols" are those that are owned by multiple `.o` files. These include
inline functions defined in `.h` files, and string literals that are de-duped
at link-time. Shared symbols are normally represented using one symbol alias
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.
#### What Other Processing Happens?
