Use GNU make pattern rules to handle multiple file output from bison.
...
With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.

Bison includes its generated header in *.cc. Generate with correct name.
...
The current bison (3.7) generates a *.cc file that includes the header
it generated. For parse.cc this would be parse.hh. Right now, we rename
this header to have a common name used in other files, but this results
in a compile error for the parse.cc file:
parse.cc:462:10: fatal error: parse.hh: No such file or directory
462 | #include "parse.hh"
| ^~~~~~~~~~
Fix this by telling bison to output the header file to the correct
filename in the first place so that we don't have to rename it.
(using the --defines instead of -d option).
This looks like a bison specific option not available in Posix yacc;
but looks like we're requiring bison anyway.

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 #103 - vvp assertion failure on part select propagation.

Flip-flops are generally modelled in behavioural code using non-blocking
assignments. This change makes the synthesised code behave the same as
the behavioural code. It's a more realistic model of a real flip-flop
too, which will always have some clock-to-output delay.

When putting a value onto a wire, the value needs to be sent to the

Force and release weren't implemented properly (or at all in the
case of real values). They need to behave the same as the force
and release operations in vthread.cc.

Optimize the vec4-stack %cmp/s and %cmpi/s instructions.
...
Magnitude compare is called a LOT, so it is worth putting some
special effort into it.

Optimize the vec4_to_index, which implements %ix/vec4 instructions.

Reduce some vector copies in %load/vec4 and %concat/vec4 instructions.
...
By clever stack manipulations, we can eliminate some vector copies,
which can improve performance.

Implement %cmp/ne and %cmpi/ne
...
These pull in the inversion of the output flags so that they more
efficiently implement != and !==, without %flag_inv instructions.

vvp implementation of copy from vec4 to vec2 can use subarray method.

The __vpiArray::set_word method should take a reference.
...
Seem to have missed a case where a vvp_vector4_t can be passed by
const reference instead of by value.
