  -----------
  clang/Basic: Replace SourceManager::getMemoryBufferForFile, NFC

Replace `SourceManager::getMemoryBufferForFile`, which returned a
dereferenceable `MemoryBuffer*` and had a `bool*Invalid` out parameter,
with `getMemoryBufferForFileOrNone` (returning
`Optional<MemoryBufferRef>`) and `getMemoryBufferForFileOrFake`
(returning `MemoryBufferRef`).
