PPC specific C2 flags: add macro PD_C2_FLAGS to global flag definitions.

Similar to PD_FLAGS, but for flags needed in the optimizing C2 compiler

Support for C calling conventions that require 64-bit ints.

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().
