The elaborator improperly allowed user function call nodes to take on
the expression width requested of them. The result was that generated
code had junk pad bits in certain cases.
In expressions, user defined functions have a clearly defined
width and the test_width expression needs to express that. Note
that the $signed/$unsigned functions are special and magical.

classes are removed from the ivl core program, and the IVL_LPM_RAM
lpm type is removed from the ivl_target API.
