  -----------
  [flang] Add support for -mrecip[=<list>] (#143418)

This patch adds support for the -mrecip command line option. The parsing
of this options is equivalent to Clang's and it is implemented by
setting the "reciprocal-estimates" function attribute.

Also move the ParseMRecip(...) function to CommonArgs, so that Flang is
able to make use of it as well.
