This patch adds support for 64 bit non-blocking delays in procedural
code. We fixed the procedural delay operator (blocking delays) earlier.
This patch mostly mimics what was done there. The continuous assignment
delay operator still needs to be fixed.
Continue cleaning up shadowed variables, flagged by turning on -Wshadow.
No intended change in functionality. Patch looks right, and is tested
to compile and run on my machine. No regressions in test suite.
This patch set covers C code, with the notable exception of
vpi/lxt_write{,2}.c.
