Henrik Gramner 9f1245eb96 x86inc: Support arbitrary stack alignments 
Change ALLOC_STACK to always align the stack before allocating stack space for
consistency. Previously alignment would occur either before or after allocating
stack space depending on whether manual alignment was required or not.
