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.

	PR target/59833

With the last change the not-aligned symbol ref markers are always set
for modes with size zero.  This is wrong since for larl the size of
the access does not matter.  This patch removes that check entirely
from s390_encode_section_info.  Modes with a size of 0 get rejected in
s390_check_symref_alignment which is used for the load/store relative
instructions to check for natural alignment.
