LineInfo uses perm_string for path.
...
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

Proper padding of constant bitwise operands
...
When evaluating bitwise binary expressions at compile time, get the
signed/unsigned padding correct. Pay special attention to the case
of $signed/$unsigned changing the signedness of the operand.

Do not MSB extend constants that already have a defined width.
...
During elaboration certain constants were getting extended with
the MSB. This patch makes that happen only if the constant does
not have a length. At this point most should have a length so
effectively every unsigned value is extended with 0.

Propagate sign for constant numbers inside $signed()/$unsigned().

Major rework of array handling. Memories are replaced with the

more general concept of arrays. The NetMemory and NetEMemory

lpm type is removed from the ivl_target API.
