pass the reason for failure up from MemoryBuffer and report it
in diagnostics when we fail to open a file. This allows us to report things like: $ clang test.c -I. test.c:2:10: fatal error: error opening file './foo.h': Permission denied #include "foo.h" ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@90276 91177308-0d34-0410-b5e6-96231b3b80d8
