Comments: llgs: fixes to PTY/gdb-remote inferior stdout/stderr handling, logging addtions.

With this change, both local-process llgs and remote-target llgs stdout/stderr
handling from inferior work correctly.

Several log lines have been added around PTY and stdout/stderr redirection
logic on the lldb client side.

Regarding remote llgs execution, see the following:

With these changes, remote llgs with $O now works properly:

$ lldb
(lldb) platform select remote-linux
(lldb) target create ~/some/inferior/exe
(lldb) gdb-remote {some-target}:{port}
(lldb) run

The sequence above will correctly redirect stdout/stderr over gdb-remote $O,
as is needed for remote debugging.  That sequence assumes there is a lldb-gdbserver
exe running on the target with {some-host}:{port}.

You can replace the gdb-remote command with a '(lldb) platform connect
connect://{target-ip}:{target-port}'.  If you do this and have a
lldb-platform running on the remote end, it will go ahead and launch
llgs for lldb for each target instance that is run/attached.

For local debugging with llgs, the following sequence also works, and
uses local PTYs instead to avoid $O and extra gdb-remote messages:

$ lldb
(lldb) settings set platform.plugin.linux.use-llgs true
(lldb) target create ~/some/inferior/exe
(lldb) run

The above will run the inferior using llgs on the local host, and
will use PTYs rather than $O redirection.

This change also removes the logging that happened after the fork but
before the exec when llgs is launching a new inferior process.  Some
aspect of the file handling during that portion of code would not do
the right thing with log handling.  We might want to go back later
and have that communicate over a pipe from the child to parent to pass
along any messages that previously were logged in that section of code.

Comments: [X86] Memory folding for commutative instructions.

This patch improves support for commutative instructions in the x86 memory folding implementation by attempting to fold a commuted version of the instruction if the original folding fails - if that folding fails as well the instruction is 're-commuted' back to its original order before returning.

This mainly helps the stack inliner better fold reloads of 3 (or more) operand instructions (VEX encoded SSE etc.) but by performing this in the lowest foldMemoryOperandImpl implementation it also replaces the X86InstrInfo::optimizeLoadInstr version and is now used by FastISel too.
