add the -mrecip driver flag and process its options
This is the front-end counterpart to D8982 (LLVM r238051).
The -mrecip option interface is based on maintaining compatibility with gcc:
https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/i386-and-x86-64-Options.html#index-mrecip_003dopt-1627
https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/RS_002f6000-and-PowerPC-Options.html#index-mrecip-2289
...while adding more functionality (allowing users to specify the number of refinement steps for each
estimate type).
