Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).
Main design goals:
* There should be no boilerplate code in each test file to support the
multiple debug info in most of the tests (custom scenarios are
acceptable in special cases) so adding a new test case is easier and
we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
have to be cleanly visible from the output of dotest.py to make
debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
happens now (displaying dwarf/dsym results separately isn't
preferable)
Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
debug info separately and this test function should call just
"self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
instance), we will generate a new test method for each debug info
format in the test class with the name "<test-function>_<debug-info>"
and remove the original test method. This way unittest2 see multiple
test methods (1 for each debug info, pretty much as of now) and will
handle the test selection and the failure reporting correctly (the
debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
multiple tests for each debug info format when the test don't have an
inferior

The problem was that if the platform wasn't compatible with the current file in the "target create" command, it wasn't finding a platform that was like it used to.
Also, the currently selected platform was being used upload the file _before_ the target was created which was incorrect as "target create a.out" might switch platforms if its architecture doesn't match, so I moved the uploading to happen after the target was created so we use the right platform (the one in the target, not the selected one).

Changes include:
- fix it so you can select the "host" platform using "platform select host"
- change all callbacks that create platforms to returns shared pointers
- fix TestImageListMultiArchitecture.py to restore the "host" platform by running "platform select host"
- Add a new "PlatformSP Platform::Find(const ConstString &name)" method to get a cached platform
- cache platforms that are created and re-use them instead of always creating a new one

Removed the distribution EXEs from FreeBSD and Ubuntu.
Added a hello-world .cpp file, and compiled it for
several platform/compiler variants:
Ubuntu 14.04 x86_64, clang 3.5 (the ubuntu1 3.5 pre variant)
Ubuntu 14.04 x86_64, gcc 4.8.2
FreeBSD 10.0 x86_64, clang 3.3
FreeBSD 10.0 x86_64, gcc 4.7.3
NetBSD 6.1 x86_64, gcc 4.5.3
I also added the NetBSD expected architecture and triple.
Note I have NetBSD not appending the version info to the
OS name, in contrast to FreeBSD.

Previously ObjectFileELF was simplifying and assuming the object file it was
looking at was the same as the host architecture/triple. This would break
attempts to run, say, lldb on MacOSX against lldb-gdbserver on Linux since
the MacOSX lldb would say that the linux elf file was really an Apple MacOSX
architecture. Chaos would ensue.
This change allows the elf file to parse ELF notes for Linux, FreeBSD and
NetBSD, and determine the OS appropriately from them. It also initializes
the OS type from the ELF header OSABI if it is set (which it is for FreeBSD
but not for Linux).
Added a test with freebsd and linux images that verify that
'(lldb) image list -t -A' prints out the expected architecture for each.
