Someone must have changed the behavior of FileSpec slightly
relating to whether or not there is a trailing backslash when calling
GetPath() and GetDirectory(). This caused ScriptInterpreterPython
to find the wrong values when initializing sys.path, and as a result
we couldn't find the lldb module.
This patch fixes the issue, and also adds a test to make sure that
GetDirectory() does not return a string containing a trailing slash.

There were two versions of DoAttachToprocessWithId. One that takes
a pid_t, and the other which takes a pid_t and a ProcessAttachInfo.
There were no callers of the former version, and all of the
implementations of this version were simply forwarding calls to
one version or the other.

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.

Summary:
This patch is the beginnings of support for Non-stop mode in the remote protocol. Letting a user examine stopped threads, while other threads execute freely.
Non-stop mode is enabled using the setting target.non-stop-mode, which sends a QNonStop packet when establishing the remote connection.
Changes are also made to treat the '?' stop reply packet differently in non-stop mode, according to spec https://sourceware.org/gdb/current/onlinedocs/gdb/Remote-Non_002dStop.html#Remote-Non_002dStop.
A setting for querying the remote for default thread on setup is also included.
Handling of '%' async notification packets will be added next.

A dummy target is used by TargetList::CreateTargetInternal to prime newly
created targets. the first time this is done it creates the dummy target. The
dummy target is created with the host platform (See
TargetList::CreateDummyTarget) which results in switching the selected platform
back to the host platform even when creating a target for a different platform.
This change avoids changing the selected platform while creating the dummy
target to prevent this side effect.
Test Plan:
./dotest.py $DOTEST_OPTS -t -p TestCreateAfterAttach.py
Tests using process attach (e.g. TestCreateAfterAttach.py, TestHelloWorld.py)

This should return the correct thing for android (to fix those failing tests),

This patch adds new default flag -fno-builtin which forces gcc to not optimize builtin functions.
For example, without this flag GCC replaces printf("hello\n") -> puts("hello") even if -O0 was specified

Summary:
NPL::Resume attempted to handle eStateStopped as a resume action. However:
- GDBRemoteCommunicationServerLLGS (the only user of NPL) never sets this action
- it could set this action in response to a vCont:t packet, but LLDB never produces this packet
- gdb-remote protocol documentation says vCont:t packet is used only in non-stop mode, but LLDB
does not support non-stop mode
- even if LLDB supported non-stop mode, this implementation of eStateStopped does something
different from what the spec says it should (according to spec, it should stop the specified
thread, but this seems to want to stop all threads).
Given the facts above, I believe we should remove this unused and untested code, as it probably
doesn't even work and removing it makes the rest of the code noticably simpler.

Summary:
Since the former-TSC events are now processed synchronously, there is no need for to protect them
with a separate mutex - all the actions are now guarded by the big m_threads_mutex.
With the mutex gone, the following functions, no longer have any purpose and were removed:
NotifyThreadCreate: replaced by direct calls to ThreadWasCreated
NotifyThreadStop: replaced by direct calls to ThreadDidStop
NotifyThreadDeath: folded into StopTrackingThread
ResetForExec: inlined as it consisted of a single line of code
RequestThreadResume(AsNeeded): replaced by direct calls to ResumeThread
StopThreads: removed, as it was never called

This is a very minor change.
Just reshuffle the elements of the log filename so that the test name
comes before the arch/compiler
Before:
Failure-x86_64-clang-TestCModules.CModulesTestCase.test_expr_with_dwarf.log
After:
Failure-TestCModules.CModulesTestCase.test_expr_with_dwarf-x86_64-clang.log
This way, results are grouped by test name, not by arch. I think this
is much more useful.
