[Support] Treat truncation of fullpath as error
If the concatenation of arguments dir and bin has at least PATH_MAX characters the call to snprintf will truncate. The result will usually not exist, but if it does it's actually incorrect to return that the path exists. (Motivated by GCC compiler warning about format truncation.) Differential Revision: https://reviews.llvm.org/D58835 llvm-svn: 356036
