  DAG: Fix expansion of DYNAMIC_STACKALLOC for StackGrowsUp targets

Can't test this since I can't directly use the default expansion for
AMDGPU. It needs to scale the amount by the wave size, rather than use
the raw byte size value.

  Log Message:
  -----------
  AMDGPU: Support non-entry block static sized allocas

OpenMP emits these for some reason, so handle them. Assume these use
4096 bytes by default, with a flag to override this. Also change the
related stack assumption for calls to have a flag.
