test_width method for functions in expressions
...
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.

Fix addressing of variable words.
...
Variable word addresses are not to be adjusted by the bit select
of the vector direction. That is a holdover from when arrays were
stored as bit vectors.

Pass local scope precision from compiler to vvp/etc.
...
This patch adds ivl_scope_time_precision() to the compiler which can
be used to extract the local scope precision. tgt-stub and tgt-vvp
have been modified to use this new function and output a value that
is appropriate. The vvp runtime has been altered to use this new
data which is accessed with the vpip_time_precision_from_handle()
function. vpiTimePrecision uses this function to return the correct
precision.

Add missing primitives and fix time units error in tgt-stub.

Add code to handle all the primitives currently defined and
fixed a power of ten error in the time units display (it is
either 10^{units} or 1e{units}, but not 10e{units}).
