e3a12b57f5 Use -E sed parameter instead of -r. 
BSD sed equivalent to -r parameter is -E and it is also supported in GNU
sed thus using -E results in support on both platforms.

84f9cd0025 Optimize compares to powers of 2 
Remove opt_compare and put comparison pass in opt_expr

assuming a [7:0] is unsigned
a >= (1<<x) becomes |a[7:x]
a <  (1<<x) becomes !a[7:x]

Additionally:
a >= 0 becomes constant true,
a < 0 becomes constant false

delete opt_compare.cc
revert opt.cc to commit b7cfb7dbd (remove opt_compare step)
