Duncan P. N. Exon Smith 51d1d585e5 clang/Frontend: Use MemoryBufferRef in FrontendInputFile (and remove SourceManager::getBuffer) ...

In order to drop the final callers to `SourceManager::getBuffer`, change
`FrontendInputFile` to use `Optional<MemoryBufferRef>`. Also updated
the "unowned" version of `SourceManager::createFileID` to take a
`MemoryBufferRef` (it now calls `MemoryBuffer::getMemBuffer`, which
creates a `MemoryBuffer` that does not own the buffer data).
