Fix some synth_* help messages 
Mostly memory_libmap arg checks; puts the checks into an else block on the `if (help_mode)` check to avoid cases like `synth_ice40` listing `-no-auto-huge [-no-auto-huge]`.
Also fix `map_iopad` section being empty in `synth_fabulous`.

9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

cf60699884 synth_ice40: Use opt_dff. 
The main part is converting ice40_dsp to recognize the new FF types
created in opt_dff instead of trying to recognize the mux patterns on
its own.

The fsm call has been moved upwards because the passes cannot deal with
$dffe/$sdff*, and other optimizations don't help it much anyway.

38a0c30d65 Get rid of dffsr2dff. 
This pass is a proper subset of opt_rmdff, which is called by opt, which
is called by every synth flow in the coarse part.  Thus, it never
actually does anything and can be safely removed.
