Support Debug Info path remapping Add support for the `-fdebug-prefix-map=` option as in GCC. The syntax is `-fdebug-prefix-map=OLD=NEW`. When compiling files from a path beginning with OLD, change the debug info to indicate the path as start with NEW. This is particularly helpful if you are preprocessing in one path and compiling in another (e.g. for a build cluster with distcc). Note that the linearity of the implementation is not as terrible as it may seem. This is normally done once per file with an expectation that the map will be small (1-2) entries, making this roughly linear in the number of input paths. Addresses PR24619. llvm-svn: 250094

Reapply "Avoid emitting redundant or unusable directories in DIFile metadata entries."" This reverts commit r348280 and reapplies D55085 without modifications. Original commit message: Avoid emitting redundant or unusable directories in DIFile metadata entries. As discussed on llvm-dev recently, Clang currently emits redundant directories in DIFile entries, such as .file 1 "/Volumes/Data/llvm" "/Volumes/Data/llvm/tools/clang/test/CodeGen/debug-info-abspath.c" This patch looks at any common prefix between the compilation directory and the (absolute) file path and strips the redundant part. More importantly it leaves the compilation directory empty if the two paths have no common prefix. After this patch the above entry is (assuming a compilation dir of "/Volumes/Data/llvm/_build"): .file 1 "/Volumes/Data/llvm" "tools/clang/test/CodeGen/debug-info-abspath.c" When building the FileCheck binary with debug info, this patch makes the build artifacts ~1kb smaller.
