This object seemed unused, so I believe we can just remove this compiler
invocation without losing any test coverage.

The DIFile used by the CU is special and distinct from the main source
file. Its directory part specifies what becomes the DW_AT_comp_dir
(the compilation directory), even if the source file was specified
with an absolute path.
To support the .dwo workflow, a valid DW_AT_comp_dir is necessary even
if source files were specified with an absolute path.

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.

entries."
This reverts commit r348154 and follow-up commits r348211 and r3248213.
Reason: the original commit broke compiler-rt tests and a follow-up fix
(r348203) broke our integrate and was reverted.
