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.

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.
