  Log Message:
  -----------
  [DAG] visitFREEZE - only fold integer types to an all ones constant

ISD::isBuildVectorAllOnes can peek through bitcasts, so this can match against FP NAN (ish) data (e.g. double (bitcast i64 -1)) under certain circumstances - bail if the type isn't an integer and let bitcast folding handle it first.

Fixes #120093
