sign-extend expressions caused this to be exposed more often.

Use SmallPtrSet instead of std::vector to eliminate duplicate uses in a
function generated with -gen-function. This prevents the output from having
multiple duplicate declarations of constants and gvals.

When printing the uses of a function (-gen-function only), make sure to
include the constants referenced by intializers of global variables.

1. Consider all possible ifcvt cases at once. No longer restricted to bottom
   up iterative approach.
2. Sort all possible cases based on a cost function. Perform the most profitable
   ones first invalidate others that target the same blocks.
3. Fixed a number of bugs related to block duplication.
