-flto with using the linker-plugin has an implicit -fwhole-program
effect which brings foo local and allows IPA-SRA to remove the
constant parameter. The testcase does not want this and breaks
even without -flto if you make foo static.
Thus the following patch makes sure this doens't happen with -flto either.
Tested on x86_64-unknown-linux-gnu, applied.
Richard.
