1c0119aa90 sf2/cells_sim.v: add IOSTD parameter to I/O cells

4543751a77 synth_sf2: add -discard-ffinit option to discard ff initial value 
sf2 ff have no initial values, but some IP cores use initial values.
In order to use those cores on sf2, it is required to discard the
initial value (to be carefully used).

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.

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.

efa278e232 Fix typographical and grammatical errors and inconsistencies. 
The initial list of hits was generated with the codespell command
below, and each hit was evaluated and fixed manually while taking
context into consideration.

    DIRS="kernel/ frontends/ backends/ passes/ techlibs/"
    DIRS="${DIRS} libs/ezsat/ libs/subcircuit"
    codespell $DIRS -S *.o -L upto,iff,thru,synopsys,uint

More hits were found by looking through comments and strings manually.
