Use gn_system_verilog() where appropriate.
...
Replace explicit comparisons against generation_flag with calls to
the gn_system_verilog helper function, both for code clarity and
to fix a couple of bugs. Also simplify the implementation of the
function, as we already rely on the generation_flag enumeration
being an ordered list.

Fix for GitHub issue #121 - correctly determine ivl_root.
...
Pull request #116 added the ability for the iverilog driver to determine
ivl_root from the location of the iverilog executable (this is needed to
support relocation at the time iverilog is installed). However, the code
did not support the possible variations in the library path name.

Fix for br1007 - out-of-range constant bit select should be a warning.
...
An out-of-range constant bit select on the LHS of an assignment was being
treated as an error, whereas an out-of range constant part select would
only result in a warning. In any other context, either case would result
in a warning, so convert the error to a warning.
In addition, all warnings for out-of-range or undefined constant bit/part
selects should be controlled by -Wselect-range.

Partial fix for br1006 - allow part selects in path declarations.
...
This just enables the compiler to parse path declarations that
contain part selects. As for bit selects, the part select is
discarded, and if elaboration of specify blocks is enabled,
the path declaration will be applied to the entire vector. If
elaboration is enabled, a warning message will now be output
when a bit or part select is discarded.
