History
Richard Osborne ad4ffce35f [XCore] Support functions returning more than 4 words. 
Summary:
If a function returns a large struct by value return the first 4 words
in registers and the rest on the stack in a location reserved by the
caller. This is needed to support the xC language which supports
functions returning an arbitrary number of return values.
