[fortran, patch] Implement POPCNT and POPPAR

Subject: [fortran, patch] Implement POPCNT and POPPAR

Please find attached a patch implementing the Fortran 2008 intrinsics POPCNT and POPPAR. They're implemented by using the existing popcount(), popcountl() and popcountll() builtins. For types larger than 'long long int' (i.e. 128 bit integer on x86_64), we call the long long variant twice on two 64-bit parts, and add the results.

Regtested on x86_64-linux, OK to commit?
