History
Benjamin Kramer 465251a7ce Fix a integer overflow in SimplifyCFG's look up table formation logic. 
If the width is very large it gets truncated from uint64_t to uint32_t when
passed to TD->fitsInLegalInteger. The truncated value can fit in a register.
This manifested in massive memory usage or crashes (PR13946).
