MPPA - Oshrximm + Mgetparam + FP is GPR10 + bug
Added Oshrximm and Mgetparam -> mmult.c divide & conqueer generates
FP is now GPR10 instead of being a mix of GPR30 and GPR32
Corrected a bug where Pgoto and Pj_l were given the same interpretation,
where in fact there's a fundamental difference : Pgoto is supposed to
have a function name (symbol), while Pj_l is supposed to have a label
name (print_label). This led to having undefinite labels in the code.
