Also add 'system-zos' as a lit feature and use it where needed.
Part of the project to eliminate special handling for triples in lit
expressions.

AIX and z/OS lack Objective-C support, so mark these tests as unsupported for AIX and z/OS.
This patch follows the same reasoning as D109060.

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.

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.

This patch passes -fdebug-prefix-map (a feature for renaming source
paths in the debug info) through to the per-module codegen options and
adds the debug prefix map to the module hash.
