8024922: PPC64 (part 116): Extend adlc to generate fields into nodes. Summary: Similar to specifying functions returning constants (as ins_avoid_back_to_back()) adlc now accepts specifications with prefix ins_field_xxx(tp) and adds field xxx of type tp to the node. Reviewed-by: kvn

8024342: PPC64 (part 111): Support for C calling conventions that require 64-bit ints. Summary: Some platforms, as ppc and s390x/zArch require that 32-bit ints are passed as 64-bit values to C functions. This change adds support to adapt the signature and to issue proper casts to c2-compiled stubs. The functions are used in generate_native_wrapper(). Adapt signature used by the compiler as in PhaseIdealLoop::intrinsify_fill(). Reviewed-by: kvn

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. Reviewed-by: kvn, cjplummer
