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.

The tile clause in OpenACC 3.0 imposes some restriction. Element in the tile size list are either * or a
constant positive integer expression. If there are n tile sizes in the list, the loop construct must be immediately
followed by n tightly-nested loops.
This patch implement these restrictions and add some tests.

OpenACC combined construct can have an optional end directive. This patch handle this
case in the parsing/unparsing with a canonicalization step. Unlike OmpEndLoopDirective,
this doesn't need a special treatment in the pre-fir tree as there is no clause attached to
a AccEndCombinedDirective.
