Lars-Peter Clausen d5306085c5 vvp: Support local flag on real variables 
The vvp parser did not accept the local flag on `.var/real`
declarations. This can happen when elaboration creates a compiler-generated
real temporary, for example when a blocking intra-assignment delay is
rewritten from:

    r = #1 1.25;

to assign the right hand side to a temporary before the delay and assign
the temporary to the target after the delay.

Add support for the local flag. Keep a VPI symbol for the variable so
`%load/real` can still resolve the label, but do not attach local real
variables to the current scope.
