Jacek Caban 350c89fa75 [llvm-lib] Write object files in reversed order.
This isn't strictly needed, but this matches how MSVC lib.exe writes to
archives, so this makes llvm-lib more compatible and simplifies comparing
output between tools.

llvm-lib should behave like "link.exe /lib" and use relative paths to describe
archive members.
First, get in a clean working directory.
RUN: rm -rf %t && mkdir -p %t && cd %t
Make foo/a.obj and foo/b.obj.
RUN: mkdir foo
RUN: llvm-mc -triple=x86_64-pc-windows-msvc -filetype=obj -o foo/a.obj %S/Inputs/a.s
RUN: llvm-mc -triple=x86_64-pc-windows-msvc -filetype=obj -o foo/b.obj %S/Inputs/b.s
RUN: llvm-lib -out:foo.lib foo/a.obj foo/b.obj
RUN: llvm-ar t foo.lib | FileCheck %s
FIXME: We should probably use backslashes on Windows to better match MSVC tools.
CHECK: foo/b.obj
CHECK: foo/a.obj
Do it again with absolute paths and see that we get something.
RUN: llvm-lib -out:foo.lib %t/foo/a.obj %t/foo/b.obj
RUN: llvm-ar t foo.lib | FileCheck %s --check-prefix=ABS
ABS: {{.*}}/foo/b.obj
ABS: {{.*}}/foo/a.obj
