[Bug tree-optimization/21520] missing PRE opportunity with operand after operand

The casts one seems to be there because we don't look through casts: 

Created value VH.14 for (charD.1) 1 
Created value VH.15 for (intD.0) VH.14 

This means that for the first cast we find a fully_constant_expression here: 
1650                              eprime = fully_constant_expression (eprime); 

but not for the second. 

I haven't looked at the other test case yet.
