  [Clang][Driver][LTO] Fix empty stats filename when in LTO mode (#71197)

Previously, if a linker argument (i.e. -Wl) is presented before any input
filenames, Gnu driver would use the InputInfo object of that argument to generate stats filename for LTO backend, causing an empty filename. This patch fixes such issue.
