Stephen Williams a2dc1e0a29 Add means for &A<> to index using a calculated index.
This is not a solution to all the problems, but is a better catch-all
then what is currently there. Allow the index field to be a T<> that
accesses the thread to get the address index.

Note that the lexor.lex currently returns the T<> as a T_SYMBOL, and the
users of T_SYMBOL objects need to interpret the meaning. This is
probably not the best idea, in light of all the other *<> formats that
now exist.

Stephen Williams 6a1235ac28 Rework parameter indexed part select up.
Indexed part select reworked to be more compact and more like the
part select.

Stephen Williams 7aebff2a86 Fix up parameter name part select
Part select of parameter names is fixed up to be structurally similar
to part select of signals, and also to behave similarly. (Though not
identically, for reason.)

Stephen Williams b31124983a Allow part selects to fall off the ends of the selected identifier
Part selects to signals are allowed to be off the ends of the signal
itself. The bits that are beyond the vector return X. This may mean
creating constant X bits on one or both ends of the result.

Cary R 7c152685dc Clean up more compiletf routines, etc.
This patch cleans up some of the code to use common compiletf
routines where appropriate. It also adds code to print the
number of extra arguments and cleans up the messages a bit.

Stephen Williams 2576543bb5 Add support for exclude of a point
Parameter value ranges support the exclude of a point as well as
range, so add the syntax to support that case. Internally it is
handled as a degenerate range, but the parse and initial elaboration
need to know about it.

Cary R e453b347f4 Add missing functions to ivl.def
This patch adds ivl_island_flag_set and ivl_island_flag_test
to the ivl.def file. This is needed by both Cygwin and MinGW.

Stephen Williams f132e09475 Fix default parameter type if localparams are present.
localparam declarations were messing up the state of parser variables
so that the default types of following parameters got messed up.

Cary R 1c51ac4ac0 For undefined memory words (size == 0) return an X vector.
If a memory word was accessed before it was defined the
code was returning a zero width vector result. Now it
returns an appropriately sized vector of 'x'.

Cary R 17a1358eb6 Remove documentation for memory opcodes.
The memory opcodes %assign/mv, %load/mv and %set/mv
were removed by a previous patch. This one removes
the documentation from opcodes.txt. It also removes
the documentation for the .mem* statements for the
same reason.

Stephen Williams 04a7f7054a Fix problem linking a-side and b-side tran branches.
Tran devices linked in series were not getting properly joined up
due to a problem with the add_branch method.

Stephen Williams e97a1ad610 Try to eliminate excessive processing recursions.
After calculating the A side of a tran[if/vp], the B side is usually
fully specified, so make an effort to push the calculated value through.

Stephen Williams e872310e4b Optimize recursive branch resolution
Recursive branch resolution was scanning every branch end, even though
many branch ends share ports and need not be repeatedly scanned. Handle
marks and flags to cut off recursion where it is not needed so as to
save much run time.
