For PR351: \
* Remove IsLibrary and GetLibraryPath, replaced by FindLibrary in ../Path.cpp \ * Implement GetSystemLibraryPaths and GetBytecodeLibraryPaths, instead of the \ GetSystemLibraryPath1 and GetSystemLibraryPath2 methods git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18862 91177308-0d34-0410-b5e6-96231b3b80d8
