Summary:
On linux, the environment variables for temp directories that lldb checks for are generally not
defined, and the temp directory computation failed. This caused expression evaluation to fall
back to creating "/tmp/lldb-*.expr" debugging files instead of the usual
"$TMP/lldb/pid/lldb-*.expr". Crucially, these files were not cleaned up on lldb exit, which
caused clutter in the /tmp folder, especially on long-running machines (e.g. builtbots). This
commit fixes lldb to use llvm::sys::path::system_temp_directory, which does the same environment
variable dance, but (!) also falls back to the P_tmpdir macro, which is how the temp directory is
defined on linux.
Since the linux temp path computation now succeeds, I needed to also modify Android path
computation to check for actual directory existence, rather then checking whether the operation
failed.

If no temp directory specified by the user on android then fall back
to /data/local/tmp what is always present on the device. It removes
the dependency of specifying TMPDIR for executing platform commands
on android.

Summary:
Fixes http://reviews.llvm.org/D8511
The original method of using dladdr() could return the incorrect relative
path if not dynamically linked against liblldb and the working directory
has changed. This is not a problem when built with python, since
ScriptInterpreterPython::InitializePrivate calls
HostInfo::GetLLDBPath(ePathTypeLLDBShlibDir, ...) and caches the
correct path before any changes to the working directory.
The /proc/self/exe approach fails if run using Python, but works for all other
cases (including for android, which doesn't have dladdr()).
So if we combine the two, we should reasonably cover all corner cases.

Summary:
ComputeSupportExeDirectory relied on ComputeSharedLibraryDirectory which was
not always reliable. Using procfs seems to be the best way to deal with it on
Linux (since it's already done on Android, might as well merge it).

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.
