Comment in tree-ssa-ccp.c:
/* ??? Should perhaps do this in fold proper. However, doing it
there requires that we create a new CALL_EXPR, and that requires
copying EH region info to the new node. Easier to just do it
here where we can just smash the call operand. */
We have to copy the EH region info for other stuff already, there was a bug
about this which caused an ICE with Honza's new testing and was fixed.
