Hi Richard,
The patch for PR100786 introduced a testcase that systematically fails on

The following avoids us ICEing doing constant folding from variables
with aliases of different types. The formerly used fold_convert
wasn't entirely correct even for the cases it handled and using
a VIEW_CONVERT_EXPR avoids the ICE. Reading from a larger alias
