Jeremy Fitzhardinge 791bad9d28 x86/paravirt: implement PVOP_CALL macros for callee-save functions
Impact: Optimization

Functions with the callee save calling convention clobber many fewer
registers than the normal C calling convention.  Implement variants of
PVOP_V?CALL* accordingly.  This only bothers with functions up to 3
args, since functions with more args may as well use the normal
calling convention.
