tree-inline: Simplify IPA-CP type conversion (PR 93385)
when callers and callees do not quite agree on the type of a
parameter, usually with ill-defined K&R or with smilarly wrong LTO
input, IPA-CP can attempt to try and substitute a wrong type for a
parameter (see e.g. gcc.dg/torture/pr48063.c). Function
tree_function_versioning attempts to handle this in order not to
create invalid gimple but it then creates the mapping using
setup_one_parameter which also handles the same situation to avoid
similar problems when inlining and in more defined way.
So this patch simply removes the conversion attempts in
tree_function_versioning itself. It is helpful for my upcoming fix of
PR 93385 because then I do not need to teach
ipa_param_body_adjustments to distinguish between successful and
unsuccessful mappings - setup_one_parameter uses force_value_to_type
for conversions which simly maps the worst cases to zero.

* tree-inline.c (tree_function_versioning): Leave any type
conversion
of replacements to setup_one_parameter and its friend
force_value_to_type.
