Tom Eccles 4cc9437a7e [flang] Set default to -ffpcontract=fast
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.
