Following RFC at https://discourse.llvm.org/t/rfc-ffp-contract-default-value/66301 This adds the `fastmath<contract>` attribute to `fir.call` and some floating point arithmetic operations (hence the many test changes). Instead of testing for this specific attribute, I am using a regular expression to match any attributes.
