[clang][FileManager] Support empty file name in getVirtualFileRef for serialized diagnostics After https://reviews.llvm.org/D90484 libclang is unable to read a serialized diagnostic file which contains a diagnostic which came from a file with an empty filename. The reason being is that the serialized diagnostic reader is creating a virtual file for the "" filename, which now fails after the changes in https://reviews.llvm.org/D90484. This patch restores the previous behavior in getVirtualFileRef by allowing it to construct a file entry ref with an empty name by pretending its name is "." so that the directory entry can be created. Differential Revision: https://reviews.llvm.org/D100428 2021-04-15 02:27:03 +08:00			`// RUN: rm -f %t.diag`
