fhdl/verilog: add simulation parameter to avoid simulation tricks in synthetizable code
...
it's generally better to have identical code between simulations and synthesis, but here tricks inserted for simulation are clearly expected to be simplified by synthesis tools, so it's better not inserting them.

migen.fhdl.structure: add Signal.like(other)
...
This is a convenience method. Signal(flen(other)) is used frequently but that
drops the signedness. Signal((other.nbits, other.signed)) would be correct but
is long.

fhdl/verilog: fix representation of negative integers
...
Give the explicit two's complement representation for the given bit width.
This results in less readable code compared to using unary minus,
but fixes a bug when trying to represent the most negative integer.

do not overload __len__, __iter__, __reversed__ as not all valid

should be different from flen([]) (the later raises an error). keep
__getitem__ as an exception that proves the rule ;)
