    The compiler check that issued a duplicate declaration error for
        a, a, a := 1, 2, 3
    was incorrectly issuing an error for
        a, a, a = 1, 2, 3
    While this is not particularly useful, it is valid Go.

For Aurelien Jarno <aurelien@aurel32.net>

On ARM soft-float, the float to double conversion doesn't convert a sNaN
to qNaN as the IEEE Std 754 standard mandates:

"Under default exception handling, any operation signaling an invalid
operation exception and for which a floating-point result is to be
delivered shall deliver a quiet NaN."

Given the soft float ARM code ignores exceptions and always provides a
result, a float to double conversion of a signaling NaN should return a
quiet NaN. Fix this in extendsfdf2.

gcc/ChangeLog:

	PR target/59833
	* config/arm/ieee754-df.S (extendsfdf2): Convert sNaN to qNaN.
