Reflow a few source files to satisfy clang-format checks, fix the Constexpr heading level in docs/ispc.rst, and bump copyright years to the current year for touched files.

 ``constexpr`` declares variables and functions that can be evaluated at
 compile time. ``constexpr`` values can be used in constant-expression
 contexts such as array sizes, short vector lengths, ``switch`` case labels,
 enumerator values, non-type template arguments, and default parameter values.
