<pre class="commit-message" style="white-space: pre-wrap">Add RELOCATABLE_STACK_START to control stack spaces
When RELOCATABLE_STACK_START is defined, the control stack, binding
stack, and sigalt stack are located wherever mmap finds room for them.
Currently only implemented for Darwin, but should work for linux and
solaris. We enable this by default on Darwin now.</pre>
