[IRSim][IROutliner] Allowing Intrinsic Calls to be Used in Similarity Matching and Outlined Regions

Due to some complications with lifetime, and assume-like intrinsics, intrinsics were not included as outlinable instructions. This patch opens up most intrinsics, excluding lifetime and assume-like intrinsics, to be outlined. For similarity, it is required that the intrinsic IDs, and the intrinsics names match exactly, as well as the function type. This puts intrinsics in a different class than normal call instructions (https://reviews.llvm.org/D109448), where the name will no longer have to match.

This also adds an additional command line flag debug option to disable outlining intrinsics.

Recommit of: 8de76bd5
Adds extra checking of intrinsic function calls names to avoid taking the address of intrinsic calls when extracting function calls.
