Use indirect calls in PowerPC JIT.
...
See PR5201. There is no way to know if direct calls will be within the allowed
range for BL. Hence emit all calls as indirect when in JIT mode.
Without this long-running applications will fail to JIT on PowerPC with a
relocation failure.

"The CWriter::GetValueName() method does not check if a value as an alias
and emits the alias name which will never be defined in the output .c
file (so the output file fails to compile). This can happen if you have
multiple inheritance with several destructors defined by clang (...D0Ev,
...D1Ev, ...D2Ev)."
