Update lrint/lrintf/lrintl for x32

Update lrint/lrintf/lrintl for x32

The x86_64 versions of lrint/lrintf/ lrintl are aliases for the long
long versions which isn't correct for x32, where exceptions must respect
overflow for 32-bit long.  Separate versions of the long functions for
x32 that convert to 32-bit long and raise the right exceptions for that
conversion, while keeping the aliases in the non-x32 case.

Tested on x86_64 and x32.  There are no code changes in libm.so on
x86_64.
