nir/algebraic: Add some logical OR and AND patterns
The new OR pattern has been seen in the wild and can end up being
generated by GLSLang. Not sure about the other two new patterns but we
may as well throw them in for completeness. While we're here, we can
drop the '@bool' specifier from the one pattern because specifying True
already implies 1-bit which basically implies boolean.
