[clang] [CIR] Upstream cir.call with scalar arguments (PR #136810)

This loop is using a bunch of traditional for loops instead of 'range-for' (and loops instead of algorithms!).  It would be a vast improvement to replace those with std::algorithms if they end up being 'simple' enough, and at least range-for loops.
