simplify-rtx: Remove non-simplifying simplification (PR77729)

If we have (X&C1)|C2 simplify_binary_operation_1 makes C1 as small as
possible.  This makes worse code in common cases like when the AND with
C1 is from a zero-extension.  This patch fixes it by removing this
transformation (twice).

	PR rtl-optimization/77729
	* simplify-rtx.c (simplify_binary_operation_1): Delete the (X&C1)|C2
	to (X&(C1&~C2))|C2 transformations.
