Just my 2 cents: we have to resurrect CallSignatureReturns PMC, move 
csr_* functions back into it and use this PMC to store pointers for 
return positions in C code. vastart/valist macros can't be restarted. An 
technically speaking we are invoking "get_results" "opcode" before 
"invoke" "opcode" on C side.
