<pre>Currently, PCH can only be written to FrontendOptions.OutputFile, leading to
complex code for managing it inside ASTUnit(used by libclang/clangd).
Having an option to write it into memory would allow to get rid of disk
accesses altogether.
(And vfs::FileSystem could be used to read it from memory).</pre>
