First cut of PowerPC(64) support in LLDB.
Summary:
This adds preliminary support for PowerPC/PowerPC64, for FreeBSD. There are
some issues still:
* Breakpoints don't work well on powerpc64.
* Shared libraries don't yet get loaded for a 32-bit process on powerpc64 host.
* Backtraces don't work. This is due to PowerPC ABI using a backchain pointer
in memory, instead of a dedicated frame pointer register for the backchain.
* Breakpoints on functions without debug info may not work correctly for 32-bit
powerpc.
