Give delay paths scope.
...
Delay paths need a scope. This helps the code generators bind the
modpaths to the correct scope. This patch doesn't actually make use
of the information, it just makes it available to code generators.

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.
