Flang diverges from the llvm coding style in that it requires braces
around the bodies of if/while/etc statements, even when the body is
a single statement.
This commit adds the readability-braces-around-statements check to
flang's clang-tidy config file. Hopefully the premerge bots will pick it
up and report violations in Phabricator.
We also explicitly disable the check in the directories corresponding to
the Lower and Optimizer libraries, which rely heavily on mlir and llvm
and therefore follow their coding style. Likewise for the tools
directory.
We also fix any outstanding violations in the runtime and in
lib/Semantics.

Create test fixture for runtime tests which enables verification
of failure cases. Test some runtime IO APIs for failure cases.
Support testing efforts in D98303. Expand on effort discussed
