RFR: 8341411: C2: remove slice parameter from GraphKit::make_load() and GraphKit::store_to_memor()

[theoweidmannoracle]

This patch removes the address type from `GraphKit::make_load()` and `GraphKit::store_to_memory()`

As https://github.com/openjdk/jdk/pull/21303 introduced asserts that check that the address type agrees with  `C->get_alias_index(_gvn.type(adr)->isa_ptr()`, passing the address type is redundant and it can be computed internally from the address.
