intel_synth: Fix help message
cyclonev has been a "supported" family since the initial commit. The old
commit message suggested to use a10gx which is incorrect.
Aside from the obvious lack of functional change due to this just being
a help message, users who were previously using "a10gx" for "cyclonev" will
also have no functional change by using "cyclonev" instead.

write_verilog: dump zero width constants correctly.
Before this commit, zero width constants were dumped as "" (empty
string). Unfortunately, 1364-2005 5.2.3.3 indicates that an empty
string is equivalent to "\0", and is 8 bits wide, so that's wrong.
After this commit, a replication operation with a count of zero is
used instead, which is explicitly permitted per 1364-2005 5.1.14,
and is defined to have size zero. (Its operand has to have a non-zero
size for it to be legal, though.)
Fixes #948 (again).
