ac10e7d96d Initial implementation of elaboration system tasks 
(IEEE1800-2017 section 20.11)

This is very useful to stop a synthesis of a parametrized block when an
illegal combination of parameters is chosen.

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.
