Consistently use Formatter's cached NumberFormat.
%f is a lot more expensive than it should be because we're not using the cached
NumberFormat (as we are for %d). Running the microbenchmark I added to the
bug (times in ms, on a Cortex A8):
old new
new Formatter %f 1732 811
String.format %d 635 651
String.format %f 1752 900
reuse Formatter %f 1521 188
Double.toString + 149 148
Double.toString append 33 33
StringBuilder.append 143 139
Bug: 1476
