Zachary Snow 640b9927fa sv: allow globals in one file to depend on globals in another 
This defers the simplification of globals so that globals in one file
may depend on globals in other files. Adds a simplify() call downstream
because globals are appended at the end.

Zachary Snow cb9f3b6abf verilog: disallow overriding global parameters 
It was previously possible to override global parameters on a
per-instance basis. This could be dangerous when using positional
parameter bindings, hiding oversupplied parameters.

Zachary Snow d738b2c127 sv: support for parameters without default values 
- Modules with a parameter without a default value will be automatically
  deferred until the hierarchy pass
- Allows for parameters without defaults as module items, rather than
  just int the `parameter_port_list`, despite being forbidden in the LRM
- Check for parameters without defaults that haven't been overriden
- Add location info to parameter/localparam declarations

Zachary Snow 10a6bc9b81 verilog: fix sizing of ports with int types in module headers 
Declaring the ports as standard module items already worked as expected.
This adds a missing usage of `checkRange()` so that headers such as
`module m(output integer x);` now work correctly.

Zachary Snow b6904a8e53 Set aside extraneous tests in simple_abc9 test suite 
New test cases on one branch may be automatically copied from simple/ to
simple_abc9/, causing failures when switching to another branch. This
updates the simple_abc9 script to set aside extraneous tests in a
non-destructive way.

- Standard data declarations can now use any integer type
- Parameters and localparams can now use any integer type
- Function returns types can now use any integer type
- Fix `parameter logic`, `localparam reg`, etc. to be 1 bit (previously 32 bits)
- Added longint type (64 bits)
- Unified parser source for integer type widths
