41b79b9ad4 8074869: C2 code generator can replace -0.0f with +0.0f on Linux 
Instead of 'fpclass', use cast float->int and double->long to check if value is +0.0f and +0.0d, respectively.

081d2454fb 8024344: PPC64 (part 112): C argument in register AND stack slot 
On PPC, the first 13 floating point arguments to C calls are passed in floating point registers. Also, all but the first 8 arguments are passed on the stack. So there can be floating point arguments that are passed on the stack and in a register. We duplicate the regs datastructure in c_calling_convention() to represent this.
