Summary:
This diff adds support in symbolic execution for calls to intrinsic
functions, to be used in lieu of adding a separate Llair instruction
for each intrinsic. This involves:
- adding skeleton support in Exec for symbolically execution an
intrinsic function call;
- exposing this in Domain;
- allowing symbolic execution of block terminators (e.g. function
call) to possibly fail; and
- generalizing Report for failing terminators.
