TRUE/FALSE simplification

There is really no need to write code like "foo != 0 ? TRUE : FALSE"
unless we had stupidly defined FALSE as something other than 0 or TRUE
as something other than 1.  The simpler "foo != 0" does just as well.
Similarly "(condition == TRUE)" or "(condition == FALSE) can be
simplified to "(condition)" and "(!condition)" respectively.

I'll note that there is reason to use "integer_expression != 0" when
assigning a bfd_boolean rather than the simpler "integer_expression",
if you expect the variable to have 0 or 1 value.  It's probably even a
good idea to not rely on implicit conversion if bfd_boolean were _Bool.
