Properly report errors for out-of-bounds constant indexed part selects.
...
(replacing assertions)
The IEEE standard either requires out-of-bounds bits to be ignored on
write, returned as 1'bx on read, or requires a compile-time error message.
The latter is easier to implement.

Fix width calculation for bit/part selects of multi-dimensioned packed arrays.
...
If we have a bit/part select that is selecting one or more sub-arrays, e.g.
wire [3:0][3:0] foo;
assign foo[1] = 4'd1;
we need to take into account the bit width of the sub-array when calculating
the bit width of the select.

Don't return packages when iterating over root modules (issue #496 )
...
The code assumed all handles stored in vpip_root_table were modules. This
is true for traditional Verilog, but not so for SystemVerilog.
Whilst here, also add support for iterating over packages.

Recognise and obey `line directives in the preprocessor (issue #488 )
...
To correctly restore the file name and line number after including a
file or expanding a macro, the preprocessor needs to be aware of the
changes introduced by `line directives. The `line directive still
needs to be passed on to the main compiler so it can track the
changes too.
To avoid duplicate error messages, the preprocessor silently ignores
invalid `line directives, relying on the main compiler to report the
errors.
