  Shrink built-in atof function a bit

Skip 'nan' and 'inf' parsing when the float() builtin
is not present as those won't be needed for the lexer.

Use x*10+c instead of shifts as it's smaller. Use more efficient check
for exponent character.

  duemilanove, grove: Keep ROM image within limits

While the atmega32p rom holds 32kB, the upper 512B hold the boot
loader, so we need to make sure the image fits within the remaining space.
