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: 8de76bd569732acae6a10fdcb0152a49f7d4cd39 Adds extra checking of intrinsic function calls names to avoid taking the address of intrinsic calls when extracting function calls.
