Sanjoy Das d04393828c [EarlyCSE] Simplify guard intrinsics ...

Summary:
This change teaches EarlyCSE some basic properties of guard intrinsics:

 - Guard intrinsics read all memory, but don't write to any memory
 - After a guard has executed, the condition it was guarding on can be
   assumed to be true
 - Guard intrinsics on a constant `true` are no-ops
