Add a pass to lower is.constant and objectsize intrinsics This pass lowers is.constant and objectsize intrinsics not simplified by earlier constant folding, i.e. if the object given is not constant or if not using the optimized pass chain. The result is recursively simplified and constant conditionals are pruned, so that dead blocks are removed even for -O0. This allows inline asm blocks with operand constraints to work all the time. The new pass replaces the existing lowering in the codegen-prepare pass and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert on the intrinsics.

; 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.
