Reformat the JIT sources.

The sources were formatted using jit-format on Windows with the
following command lines in the following order:

    `jit-format.cmd -o Windows -b Checked -a x64 -f`
    `jit-format.cmd -o Windows -b Debug -a x64 -f`
    `jit-format.cmd -o Windows -b Release -a x64 -f`

The versions of clang-format and clang-tidy that were invoked by
jit-format were:
