[PATCH] Do not generate a __morestack prologue, for functions with a stack of size zero

[Florian Zeitz]

Hi Tim,

Thank you for reviewing this change.
As this is my first time going through this process, I'm admittedly not sure what the next step towards getting this committed is.
Is it common to explicitly ask someone with commit access to do the commit?

Regards,
Florian
