Sure. I shall move this in separate patch.
Yes this is useful in -O0 case. the testcase is added with the current patch as
"callsitepar-fastisel.ll". Though the IR is generated from fortran program
(mentioned in test case). But I think it is not specific to fortran. Since even
with -O0 many optimizations work, it is very much possible that parameter gets
optimized out.
