[PR/middle-end 106819] NANs can never be a singleton
Possible NANs can never be a singleton, so they will never be
propagated. This was the intent, and then the signed zero code crept
in, and was mistakenly checked before the NAN.
PR/middle-end 106819
gcc/ChangeLog:
* value-range.cc (frange::singleton_p): Move NAN check to the top.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/pr106819.c: New test.
