The parameter_omit tests have different expectations depending on whether the
regression is run in the default Verilog mode or with force SystemVerilog.
The old list files modelled this by registering the same tests in both
regress-vlg.list and regress-fsv.list.
Move the tests to JSON descriptors. Use the existing force-sv override for the
forms that are valid SystemVerilog, and keep the implicit type cases as CE in
both modes. This also runs the tests through the additional configurations
supported by vvp_reg.py, providing better coverage in CI.

The br_gh1385a, br_gh1385b, and br_gh1385c JSON descriptors mark the vlog95
variants as compile errors. The enum typedefs are translated correctly, so the
compile error expectation causes the tests to fail when compilation succeeds.
Remove the stale overrides and run the translated tests through vlog95.

Check that a named binding selector can have the same text as a visible typedef
name. Cover named module port connections, named parameter overrides, and named
task, function and constructor arguments.
Also check that a modport simple port selector can shadow a visible typedef
name. Modport simple port aliases share the same parser rule but declare the
modport-visible name rather than binding to an existing formal.

Check that event declarations can use visible type identifiers as event names.
Also check that the resulting named event can be triggered and waited on.

Check that visible type identifiers can be reused as named block labels. Cover
procedural `begin` blocks, fork blocks, and conditional generate blocks. Also
check matching end labels where the grammar consumes the shared `label_opt`
rule.
The generate test keeps the existing vlog95 compile-error expectation because
named generate scopes are not translated by the vlog95 target.

Check that a package declaration can use a visible type identifier as its
package name. Also check that the resulting package scope can be selected with

Check that UDP primitive and port names can shadow visible type identifiers.
Cover old-style UDP declarations, including input and output declarations and
the initial target, as well as ANSI-style UDP port declarations.

Check that UDP initial values on non-registered outputs generate compile
errors for both old-style and ANSI-style UDP declarations. Also check that
conflicting UDP port declarations generate an error and that a valid
ANSI-style `output reg` initializer is accepted.

Check that enum item names can shadow visible type identifiers. Cover plain enum
items as well as the counted and ranged enum item sequence forms.

Check that function and task declarations can use a visible type identifier as
the declaration name. Cover both ANSI declarations and the non-ANSI forms where
the name is parsed without a separate return type or port list.
Also check class method declarations where the method name is the same as the
enclosing class name. Add GitHub issue #670 coverage for the `function void`
case using the issue-based regression naming scheme.

Check that visible type identifiers can be shadowed by value parameter names
and by type parameter names. Cover ordinary parameter declarations, typed
parameter declarations, and parameter port list declarations separately.

Check that a class property can have the same name as a type declared in
an outer scope, or a type imported through a wildcard import. Also check
that a class property can have the same name as the class itself.

Check that automatic variables referenced through an assignment pattern in a
procedural `force` statement are rejected.

Check that the repeat count expression of a non-blocking intra-assignment
event control can reference an automatic task argument. The repeat count is
evaluated when the assignment is scheduled, so the automatic variable is not
referenced after the task scope is freed.

Check that variable and net declaration names can shadow a visible type
identifier. Check this for explicit data type declarations, `var` declarations,
and net declarations.
Check that task and function formal argument names can shadow a visible type
identifier, and that typed arguments still use the visible typedef when an
argument name follows.
Check ambiguous module port declarations where a type identifier can be either
the port name or the port type, with and without dimensions, and that
declaration lists continue to use the type selected by the first ambiguous
declarator. Cover both ANSI and non-ANSI module port declarations.

Check that visible type identifiers can be shadowed by declarations in
other namespaces or nested scopes. Keep each grammar category in a

Also check that package import and export items can name a type
identifier.

Check that unary real minus preserves the sign or bit pattern for zero,
NaN, and infinity. Each test starts with the positive value, negates it,
and then negates the result back to the positive value.

Check that the vvp code generator emits a -0.0 real constant with its
sign bit set, so the compiled value matches the runtime real value. The
sign used to be detected with (value < 0), which is false for IEEE 754
-0.0, and a -0.0 constant was turned into +0.0.
