Check for byte order correctness in GDBRemoteCommunicationClient::GetCurrentProcessInfo.

This is useful for checking inconsistencies between what the remote debug server thinks we are debugging and we think we are debugging. This follows the check for pointer byte size done just above.

Change by Stephane Sezer.

Tested:
Ubuntu 14.04 x86_64, llvm-3.5-built lldb
MacOSX 10.9.4, Xcode-Beta(2014-09-09)-built lldb.
