Parse and elaborate unique and priority case statements
...
The unique, unique0, and priority keywords can decorate case statements
to tell the run time (or synthesis) to do extra tests (or make extra
assumptions). These tests are not implemented in the vvp run time, but
now the decorations make it to the code generators.

Properly implement casts from strings and dynamic arrays to vectors.
...
As discussed on iverilog-devel (2018-03-09), the existing implementation
(using Icarus-specific vpi functions) only worked with assignments to
simple variables, and could not be easily modified to work more generally.
So use the new vvp instructions added in the previous two commits.

Fix GitHub issue #244 : handle mixed signed/unsigned power operations.

The signed version of the power operation in vvp should only be used
if the exponent is signed. Both signed and unsigned versions will
produce the correct result regardless of the type of the base operand,
provided it has been appropriately extended to the result size.

Handle mixed continuous and non-blocking assignments to same vector.
...
SystemVerilog allows a mixture of procedural and continuous assignments
to be applied to different parts of the same vector. The previous attempt
to make this work for non-blocking assignments was flawed (see preceding
fix for vvp_fun_part_pv::recv_vec4_pv). Instead, handle this case by
converting the non-blocking assignment into a delayed force statement,
which matches the way mixed continuous and blocking assignments are
handled.

Fix for GitHub issue #96 - support mixed constant/variable delays in vvp.
...
If all three rise/fall/decay delay values are constant, we can use
the vvp .delay statement variant that takes three literal numbers.
If not, we have to use the variant that takes three net inputs. If
some of the delay values are constant, we need to create constant
drivers for those delay inputs.
