Auto merge of #122645 - saethlin:portable-mir-opt-tests, r=Nadrieril

Remove some only- clauses from mir-opt tests

Derived from https://github.com/rust-lang/rust/pull/122295

Many of these tests were originally codegen tests, and MIR is more trivially portable than LLVM IR. We simply don't need to restrict the platform in most cases.
