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.

11fb1aa5a4 [flang] Upstream the lowering of the while loop
Upstream the code for handling while loops from the fir-dev branch at
https://github.com/flang-compiler/f18-llvm-project/tree/fir-dev/

Also add tests.

The while loop is lowered to a header block that checks the loop
condition and branches either to the exit block or to the body of the
loop. The body of the loop will unconditionally branch back to the
header.
