Obtain actual 0-parameter count for OR(), AND() and 1-parameter functions
OR and AND for legacy infix notation are classified as binary
operators but in fact are functions with parameter count. In case
no argument is supplied, GetByte() returns 0 and for that case the
implicit binary operator 2 parameters were wrongly assumed.
Similar for functions expecting 1 parameter, without argument 1
was assumed. For "real" unary and binary operators the compiler
already checks parameters. Omit OR and AND and 1-parameter
functions from this implicit assumption and return the actual 0
count.
