  Log Message:
  -----------
  [flang] Add support for -mprefer-vector-width=<value> (#142073)

This patch adds support for the -mprefer-vector-width= command line
option. The parsing of this options is equivalent to Clang's and it is
implemented by setting the "prefer-vector-width" function attribute.
