Kousik Kumar 4abac53302 In openFileForRead don't cache erroneous entries if the error relates to them being directories. Add tests.
Summary:
It seems that when the CachingFileSystem is first given a file to open that is actually a directory, it incorrectly
caches that path to be errenous and throws an error when subsequently a directory open call is made for the same
path.
This change makes it so that we do NOT cache a path if it turns out we asked for a file when its a directory.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
