clear -Wextra-semi-stmt warnings

This is available with clang. Clears warnings of the form:
  warning: empty expression statement has no effect; remove unnecessary

As a side-effect it also clear a few -Wpedantic warnings with gcc:
  warning: ISO C does not allow extra ';' outside of a function
    [-Wpedantic]
