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.
