printf core: replace if(0) blocks around switch cases with explicit gotos

this is purely a readability change, not a functional one. all of the
integer format cases use a common tail for handling precision logic
after the string representation of the number has been generated. the
code as I originally wrote it was overly clever in the aim of making a
point that the flow could be done without goto, and jumped over
intervening cases by wrapping them in if (0) { }, with the case labels
for each inside the conditional block scope.

this has been a perpetual source of complaints about the readability
and comprehensibility of the file, so I am now changing it to
explicitly jump to the tail logic with goto statements.
