[PATCH] D11815: Pass subtarget feature "force-align-stack"

Hal, do you have any thoughts on the points Vasileios brought up? Currently, many of the targets don't guarantee that the realigned stack is at least as aligned as the default alignment required by the ABI. Is this the behavior end-users expect when they use -mstackrealign on the command line?Fixing this is beyond the initial scope of this patch and probably should be done in a separate patch, but I want to make sure the patch I'll end up committing won't make it harder to fix this problem.
