The precedence of operators in rtlanal has been adjusted to ensure that all binary operators have a higher precedence than all unary operators. This change canonicalizes existing AArch64 patterns, ensuring that expressions like some binary > some unary > some other binary are correctly ordered during RTL analysis. This change affects how RTL expressions are simplified and matched during code generation.
