Disabling the package item injection routine used in the enum conversion
when there were no items to inject exposed cases where conversions would
generate duplicate declarations. The hierarchical constant and param
type conversions were trivially affected. The package conversion could
inject class items within a generate region and then re-inject them
outside of that generate region. The package conversions now uses an
upgraded generate region flattening utility to ensure injected class
items are seen. This also includes coverage for a conflict which
occurred even without the enum conversion change.
- remove needless comments generated during interface conversion
- filter null statements even in verbose mode
- hoist trace comment statements if doing so would prevent the need to
wrap a task or function body in a block
- add traces for global declarations
- add traces for parameter declaration lists
- add traces for module items within generate blocks
- avoid generating duplicate traces before declarations
- fix int type conversion not visiting function return type expressions
- add node-based traversal for decls visiting top level types and exprs
- explicit expr and type recursion in package ident resolution
- expose mapBothM traversal helper
- avoid double-visiting of decl types in certain conversions
Data.Hashable can produce hashes differing little in their upper bits if
only the last character of the string is changed. Because we were using
the upper bits of the hash in shortHash, this could lead to avoidable
hash collisions. This change includes minor simplification optimizations
which surfaced this collision in the existing struct_ident_scope test.

depend on the size of the string parameter

variables declared outside of the looop

renamed when creating new type parameter modules
