[PlaceSafepoints] Clamp NoStatepoints to true This change permanently clamps -spp-no-statepoints to true (the code deletion will come later). Tests that specifically tested PlaceSafepoint's ability to wrap calls in gc.statepoint have been moved to RS4GC's test suite. llvm-svn: 259096

[PlaceSafepoints] Introduce a -spp-no-statepoints flag Summary: This change adds a `-spp-no-statepoints` flag to PlaceSafepoints that bypasses the code that wraps newly introduced polls and existing calls in gc.statepoint. With `-spp-no-statepoints` enabled, PlaceSafepoints effectively becomes a safpeoint **poll** insertion pass. The eventual goal is to "constant fold" this option, along with `-rs4gc-use-deopt-bundles` to `true`, once clients using gc.statepoint are okay doing so.
