    Driver: Add new -truncate option

    This commit adds a new option to the driver that truncates one file after
    linking.

    Tested likeso:

    $ gcc hello.c -c
    $ du -h hello.o
    4.0K  hello.o
    $ gcc hello.o -truncate hello.o
    $ ./a.out
    Hello world
    $ du -h hello.o
    $ 0   hello.o

    $ gcc hello.o -truncate
    gcc: error: missing filename after '-truncate'

    The motivation for adding this is PR110710. It is used by lto-wrapper to
    truncate files in a shell-independent manner.
