Log Message:
lint: merge duplicate grammar rules for __alignof__ expr

This allows expressions like '__alignof__(ptr)->member', just as with
'sizeof'.

The upper rule in the grammar was preferred over the lower rule since it
shifted the T_LPAREN instead of reducing unary_expression.  Its
implementation invoked undefined behavior if the expression was NULL
since it didn't assign anything to $$.
