Remove out-of-line atomic implementation for PowerPC

Only support inline assembler with GCC. Support for xlC or other
compilers is not provided or tested. The files in
src/corelib/arch/vxworks only supported out-of-line PowerPC, so
remove it as well.

The xlC compiler seems to support GNU-style inline assembly, which we
prefer. Anyone wishing to support that compiler again should first test
if the inline assembly (the prefered method) works. See
