Charlotte 3571bf2c2d fmt: fuzz, remove some unnecessary busywork 
Removing some signed checks and logic where we've already guaranteed the
values to be positive.  Indeed, in these cases, if a negative value got
through (per my realisation in the signed fuzz harness), it would cause
an infinite loop due to flooring division.

Charlotte 2ae551c0af fmt: fuzz, fix (remove extraneous + incorrect fill) 
"blk + chunks" is often an overrun, plus the fill is unnecessary; we
throw blk away immediately.

Charlotte 52dc397a50 cxxrtl: don't use signed divide with unsigned/pos values 
Incorrect for unsigned, wasted effort for positive signed.

Charlotte d9e4582558 fmt: handle part with unspecified padding in `emit_rtlil` 
e.g. `$displayh(8'ha)` won't have a padding set, because it just gets
`lzero` set instead by `compute_required_decimal_places`.

It also doesn't have a width.  In this case, we can just fill in a dummy
(unused) padding.  Either space or zero would work, but space is a bit
more distinct given the width field follows.

Also omit writing the width if it's zero.  This makes the emitted ilang
a little cleaner in places; `{8:> h0u}` is the output for this example,
now.  The other possible extreme would be `{8:>00h0u}`.

Charlotte 28bd3a4b5d fmt: don't overrun fmt string buffer 
For input like "{", "{1", etc., we would exit the loop due to
`i < fmt.size()` no longer being the case, and then check if
`++i == fmt.size()`.  That would increment i to `fmt.size() + 1`,
and so execution continues.

The intention is to move i beyond the ':', so we do it only in that
case instead.

Charlotte 51d9b73107 fmt: tests completing again 
We need to invoke "read_verilog" manually, since the default action on
input files is to defer processing.  Under such conditions, we never
simplify the AST, and initial $prints never execute.
