Summary:
The StackUsesFrames and FunctionCallsChangeCFA virtual functions
aren't used anywhere and aren't overridden by anything.
They were introduced when the ABISysV_ppc* code was added and weren't
used at the time. The review for the commit that added them can be
found at http://reviews.llvm.org/D5988
The commit comment notes that backtraces don't yet work:
Backtraces don't work. This is due to PowerPC ABI using a
backchain pointer in memory, instead of a dedicated frame
pointer register for the backchain.
So there is a possibility these were added with the intent of using
them in the future.

Previously we haven't cleaned up the working directory we created on
the remote platform and because of it we run out of storage on some
android device/emulator (caused by the 2x increase of the number of
test cases because of dwo).

dwo symbol files are generated when code compiled with the "-gsplit-dwarf"
command option (https://gcc.gnu.org/wiki/DebugFission). This CL modifies
the test system to run tests with inferiors compile with the "-gsplit-dwarf"

Go tests fail on Ubuntu 14.04's go1.2.1. This change puts a minimum
go version in the skipUnlessGoInstalled() decorator of go1.3.0.
Go maintainers are encouraged to modify as needed. For now this fixes
failing tests on Ubuntu 14.04 x86_64 buildbots with stock distro go installed.

4-core CPUs have a hard time keeping up with the number of debuggers
we were simultaneously spawning. This leads to a timeout, which
leaves processes hanging around in "suspended mode", which can't be
killed with signals.

Rename the python source file for DataFormatterOSTypeTestCase to match
the purpose of the test and to avoid a name conflict with
DataFormatterBoolRefPtr. The name conflict caused a race condition in
the test runner what we have to address separately.

Summary:
When `module_spec.GetFileSpec().GetDirectory().AsCString()` returned a `nullptr` this line caused a segmentation fault:
`std::string module_directory = module_spec.GetFileSpec().GetDirectory().AsCString()`
Some context:
I was remote debugging an executable built with Clang in an Ubuntu VM on my Windows machine using lldb-mi. I copied the executable and nothing else from the Ubuntu VM to the Windows machine.
Then started lldb-server in the Ubuntu VM:
```
./bin/lldb-server gdbserver *:8888 -- /home/enlight/Projects/dbgmits/build/Debug/data_tests_target
```
And ran `lldb-mi --interpreter` on Windows with the following commands:
```
-file-exec-and-symbols C:\Projects\data_tests_target
-target-select remote 192.168.56.101:8888
-exec-continue
```
After which the segmentation fault occurred at the aforementioned line. Inside this method `module_spec.GetFileSpec()` returns an empty `FileSpec` (no dir, no filename), while `module_spec.GetSymbolFileSpec().GetFilename()` returns `"libc-2.19.so"`.
Patch thanks to Vadim Macagon.

SUMMARY:
This patch includes:
1. Emulation of prologue/epilogue and branch instructions for microMIPS.
2. Setting up alternate disassembler (to be used for microMIPS).
So there will be two disassembler instances, one for microMIPS and other for MIPS.
Appropriate disassembler will be used based on the address class of instruction address.
3. Some of the branch instructions does not have fixed sized delay slot, that means delay slot instruction can be of 2-byte or 4-byte.
For this "m_next_inst_size" has been introduced which stores the size of next instruction (i.e size of delay slot instruction in case of branch).
This can be used wherever the size of next instruction is required.
4. A minor change to use mips32 register names instead of mips64 names.

This patch adds a new command 'language renderscript allocation list' for printing the details of all loaded RS allocations.
In order to work out this information lldb JITs the runtime for the data it wants.
This has a penalty of a couple seconds latency, so is only done once for each allocation and the results cached.
If the user later wants to recalculate this information however, they can force lldb to do so with the --refresh flag.

When the readline target exists (only for non-Android Linux currently),
ensure that target is made a dependency of the finish_swig python-wrap-up
steps. This ensures it is built when building the lldb target.

The concept here is that languages may have different ways of communicating
results. In particular, languages may have different names for their result
variables and in fact may have multiple types of result variables (e.g.,
error results). Materializer was tied to one specific model of result handling.
Instead, now UserExpressions can register their own handlers for the result
variables they inject. This allows language-specific code in Materializer to
be moved into the expression parser plug-in, and it simplifies Materializer.
These delegates are subclasses of PersistentVariableDelegate.
PersistentVariableDelegate can provide the name of the result variable, and is
notified when the result variable is populated. It can also be used to touch
persistent variables if need be, updating language-specific state. The
UserExpression owns the delegate and can decide on its result based on
consulting all of its (potentially multiple) delegates.
The user expression itself now makes the determination of what the final result
of the expression is, rather than relying on the Materializer, and I've added a
virtual function to UserExpression to allow this.

TestDiamond and TestSBValueCast were due to a bug in clang. That
bug has been fixed, so xfail is removed. However fixing that bug
exposed another bug in clang, which is not yet fixed. That bug
causes one test to start crashing, and another to fail unexpectedly
so the status of those tests is updated as well.

This is meant to support languages that can do some sort of bridging from<-->to these ObjC types via types that statically vend themselves as Cocoa types, but dynamically have an implementation that does not match any of our well-known types, but where an introspecting formatter can be vended by the bridged language
