This commit updates a comment in tree-ssa-forwprop.cc to provide a clearer explanation of why the tree_to_uhwi function is considered safe. The comment now emphasizes that the operation is safe because the result is always less than TYPE_PRECISION, providing better context for developers reading the code.
