Add semihosting support for PPC64. This implementation is
based on the standard for ARM semihosting version 2.0, as
implemented by QEMU and documented in
https://github.com/ARM-software/abi-aa/releases
The PPC64 specific differences are the following:
Semihosting Trap Instruction: sc 7
Operation Number Register: r3
Parameter Register: r4
Return Register: r3
Data block field size: 64 bits
Where is the independent specification which defines that
this is the ABI for PPC semihosting? You should provide the
URL for that in a comment somewhere.
