[PATCH] Fix hardcoded stack probe space

[David Majnemer]

This is looking great so far.

Please update the LangRef with your new function attribute, the file is docs/LangRef.rst.

It should go with all the others: http://llvm.org/docs/LangRef.html#function-attributes
Be sure to mention that this attribute only has an effect on specific targets (MingW, Cygwin, MSVC) and that other targets will ignore the attribute.
