[PATCH][RFC] Minuscule patch to remove apparently accidental break from switch

[Simon Baldwin]

An apparently misplaced break statement within simplify_binary_operation_1()
causes calls to simplify_associative_operation() for xor operations to
potentially be missed.

This patch removes the break, enabling simplify_associative_operation().

Regression tested on i386 against the full g++ testsuite.

	* simplify-rtx.c (simplify_binary_operation_1): Removed erroneous
	break that was preventing simplify_associative_operation() for xor.
