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.

b111ea1228 xilinx: Still map LUT7/LUT8 to Xilinx specific primitives. 
Then if targeting vpr map all the Xilinx specific LUTs back into generic
Yosys LUTs.

3aa4484a3c Consistent use of 'override' for virtual methods in derived classes. 
o Not all derived methods were marked 'override', but it is a great
  feature of C++11 that we should make use of.
o While at it: touched header files got a -*- c++ -*- for emacs to
  provide support for that language.
o use YS_OVERRIDE for all override keywords (though we should probably
  use the plain keyword going forward now that C++11 is established)

d6bdefd2e9 Improving vpr output support. 
* Support output BLIF for Xilinx architectures.
 * Support using .names in BLIF for Xilinx architectures.
 * Use the same `NO_LUT` define in both `synth_ice40` and
  `synth_xilinx`.
