Detailed Description

Information about a FileID, basically just the logical file that it represents and include stack information.

Each FileInfo has include stack information, indicating where it came from. This information encodes the #include chain that a token was expanded from. The main include file has an invalid IncludeLoc.

FileInfo should not grow larger than ExpansionInfo. Doing so will cause memory to bloat in compilations with many unloaded macro expansions, since the two data structurs are stored in a union in SLocEntry. Extra fields should instead go in "ContentCache *", which stores file contents and other bits on the side.
