[ARM] Fix PR target/59833
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/c/ChangeLog:

subclass.
(find_closest_macro_cpp_cb): Move to spellcheck-tree.c.

same location as last time, don't skip if we have fix-it hints.
Clarify the skipping logic by converting it from one "if" clause
