format: Check for NaN when rendering doubles
- The result of 0.0/0.0 was being rendered as a lot of zeroes in the integer portion, as in this example: DBGvpp# show physmem 0: 16 objects, 576k of 582k used, 3k free, 0 reclaimed, 2k overhead, 16380k capacity alloc. from small object cache: 0 hits 0 attempts (0.00%) replacements 0 alloc. from free-list: 0 attempts, 0 hits (0.00%), 0 considered (per-attempt 0.00) alloc. from vector-expand: 16 allocs: 16 73643.06 clocks/call frees: 0 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.00 clocks/call - Add two macros to vppinfra/math.h that use compiler builtins to check for NaN and Infinity and then use them in format_float().
