Summary:
SIGPROF is used for profiling processes (with google-perftools for
instance), which results in the inferior receiving a SIGPROF from the
kernel every few milliseconds. Instead of stopping the debugging session
and notifying the user of this, we should just pass the signal and keep
running.
This follows the behavior we have in UnixSignals.cpp.
Test Plan: Run LLDB on linux with a binary using google-perftools, see that execution gets interrupted all the time because we receive SIGPROF. Apply the patch, everything works fine.

Also moves NativeRegisterContextLinux* files into the Linux directory.
These, like NativeProcessLinux, should only be built on Linux or a cross
compiler with proper headers.

This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64.
(More architectures coming soon).
Not every debugserver option is covered yet. Currently
the lldb-gdbserver command line can start unattached,
start attached to a pid (process-name attach not supported yet),
or accept lldb attaching and launching a process or connecting
by process id.
The history of this large change can be found here:

Until mid/late April, I was not sharing the work and continued
to rebase it off of head (developed via id tfiala@google.com). I switched over to
user todd.fiala@gmail.com in the middle, and once I went to github, I did
merges rather than rebasing so I could share with others.
