[cfe-commits] [PATCH] Target specific max stack alignment

The attached patch allows targets to specify a max stack alignment.  The goal is to prevent wasted stack space when locals are over aligned.  For example, the vector_size attribute infers the alignment to be the size of the vector unless explicitly set.  I've also added a warning to inform a user  when the target is enforcing a max alignment less then what they've explicitly requested.  Please let me know what you think..
