Unconditionally add AllocTokenPass to the optimization pipelines, and ensure that it runs last in LTO backend pipelines. The latter ensures that AllocToken instrumentation can be moved later in the LTO pipeline to avoid interference with other optimizations (e.g. PGHO) and enable late heap-allocation optimizations. In preparation of removing AllocTokenPass being added by Clang, add support for AllocTokenPass to read configuration options from LLVM module flags. To optimize given the pass is now runs unconditionally, only retrieve TargetLibraryInfo and OptimizationRemarkEmitter when necessary.

; The IR below was crafted so as:
|
|
; 1) To have a loop, so we create a loop pass manager
|
|
; 2) To be "immutable" in the sense that no pass in the standard
|
|
; pipeline will modify it.
|
|
; Since no transformations take place, we don't expect any analyses
|
|
; to be invalidated.
|
|
; Any invalidation that shows up here is a bug, unless we started modifying
|
|
; the IR, in which case we need to make it immutable harder.
