Summary:
This was originally http://reviews.llvm.org/D8709 , but I didn't commit it correctly.
Since then GetSupportedArchitectureAtIndex() has been changed. That change, http://reviews.llvm.org/D9511 , breaks non-x86 linux implementations, so this change goes back to the old implementation and adds remote linux support from D8709.
D8709 summary:
The Linux Platform currently will only say the Host architecture is supported. This patch retains that behavior for the Host Platform, but adds a list of architectures for the Remote Platform.

Removed some unused variables, added some consts, changed some casts
to const_cast. I don't think any of these changes are very
controversial.

Updated PlatformLinux::GetSupportedArchitectureAtIndex to call the
PlatformRemoteGdbServer::GetSupportedArchitectureAtIndex if connected remotely.
This should return the correct thing for android (to fix those failing tests),
and is also working for mac to linux.
Test Plan:
./dotest.py $DOTEST_OPTS -t -p TestCallStdStringFunction.py
The above still passes when running mac->linux indicating it successfully
identified PlatformLinux as the target platform and converted the mmap options
correctly.

Summary: The Linux Platform shouldn't care about the Vendor field in the Triple. Currently it allows a value of "PC", or "unknown" if LLDB was built on Linux. This patch removes that check, so the Vendor field isn't touched. This will allow the Linux Platform to be created when using a Triple of *-*-Linux.

Converts the MAP_PRIVATE and MAP_ANON options to the target platform constants
(on which the call runs) rather than using those of the compiled host.
Test Plan:
Run test suite, the following tests requiring memory allocation / JIT support
begin passing when running mac -> linux:
Test11588.py
TestAnonymous.py
TestBreakpointConditions.py
TestCPPStaticMethods.py
TestCStrings.py
TestCallStdStringFunction.py

Previously the remote module sepcification was fetched only from the
remote platform. With this CL if we have a remote process then we ask it
if it have any information from a given module. It is required because
on android the dynamic linker only reports the name of the SO file and
the platform can't always find it without a full path (the process can
do it based on /proc/<pid>/maps).

The file path is currently required on android because the executables
only contain the name of the system libraries without their path. This
CL add an extra field to the qModuleInfo packet to return the full path
of a modul and add logic to locate a shared module on android.

Summary:
This patch fixes SDK selection in the following case:
```
platform select remote-ios --sysroot "/Users/IliaK/Library/Developer/Xcode/iOS DeviceSupport/8.1.2 (12B440)" --build 12B440 --version 8.1.2
target create --arch arm64 "~/Project1.app"
```
Currently the lldb selects a first SDK version (in name order) in directory and then updates it after the device is connected. This approach ignores user's arguments and actually "platform select" command doesn't make sense.
After this patch, lldb takes a SDK which matches to user's arguments.

Summary:
starting a debug session on linux with -o "process launch" lldb parameter was failing since
Target::Launch (in sychronous mode) is expecting to be able to receive public process events.
However, PlatformLinux did not set up event hijacking on process launch, which caused these
events to be processed elsewhere and left Target::Launch hanging. This patch enables event
interception in PlatformLinux (which was commented out).
Upon enabling event interception, I noticed an issue, which I traced back to the inconsistent
state of public run lock, which remained false even though public and private process states were
"stopped". I addressed this by making sure the run lock is "stopped" upon exit from
WaitForProcessToStop (which already had similar provisions for other return paths).
Test Plan: This should fix the intermittent TestFormats failure we have been experiencing on Linux.

Debugger.h is a huge file that gets included everywhere, and
FormatManager.h brings in a ton of unnecessary stuff and doesn't
even use anything from it in the header.

Instead of lldb calling the ptrace APIs directly, it launches an llgs
instance and communicates with it via the remote debug protocol.
This has two advantages.
There is more code shared between the remote debugging code path
and the local debugging code path. If a feature works in remote, it
probably works locally and vice-versa.
It makes us more architecturally similar to OSX (which also does
local debugging via a connection to debugserver).
This path is called LLGS local. We think that this configuration is
now at parity with (or better than) local linux debugging.
It is currently invoked if you have an environment variable defined
"PLATFORM_LINUX_FORCE_LLGS_LOCAL"
We would like to switch to LLGS local as the default path and only
use the non-LLGS path if someone has an environment variable defined
"PLATFORM_LINUX_DISABLE_LLGS_LOCAL"
Later, if all goes well, we would like to remove non-LLGS local
debugging support to simplify the codebase and avoid confusion.

Summary:
this also gets rid of a compiler warning in release builds by using a dynamically allocated
buffer. Therefore, a size assertion is not necessary (and probably should have been an error in
the first place).
