a4c04d1b90 ast: fix dump_vlog display of casex/casez 
The first child of AST_CASE is the case expression, it's subsequent
childrean that are AST_COND* and can be used to discriminate the type of
the case.

7d014902ec Fix digit-formatting calculation for small numbers. 
Calling log10() on zero causes a non-sensical value to be calculated. On some
compile options, I've observed yosys crashing with an illegal
instruction (SIGILL).

To make it safe, fix the calculation to do a range check; wrap it a
decimal_digits() function, and use it where the previous ceil(log10(n)) call
was used. As a side, it also improves readability.

1419c8761c Fix constants bound to redeclared function args 
The changes in #2476 ensured that function inputs like `input x;`
retained their single-bit size when instantiated with a constant
argument and turned into a localparam. That change did not handle the
possibility for an input to be redeclared later on with an explicit
width, such as `integer x;`.

0d8e5d965f Sign extend port connections where necessary 
- Signed cell outputs are sign extended when bound to larger wires
- Signed connections are sign extended when bound to larger cell inputs
- Sign extension is performed in hierarchy and flatten phases
- genrtlil indirects signed constants through signed wires
- Other phases producing RTLIL may need to be updated to preserve
  signedness information
- Resolves #1418
- Resolves #2265
