Various unwinder work.
Most of the changes are to the FuncUnwinders class -- as we've added
more types of unwind information, the way this class was written was
making it a mess to maintain. Instead of trying to keep one
"non-call site" unwind plan and one "call site" unwind plan, track
all the different types of unwind plans we can possibly retrieve for
each function and have the call-site/non-call-site accessor methods
retrieve those.
Add a real "fast unwind plan" for x86_64 / i386 -- when doing an
unwind through a function, this only has to read the first 4 bytes
to tell if the function has a standard prologue sequence. If so,
we can use the architecture default unwind plan to backtrace
through this function. If we try to retrieve the save location for
other registers later on, a real unwind plan will be used. This
one is just for doing fast backtraces.
Change the compact unwind plan importer to fill in the valid address
range it is valid for.
Compact unwind, in theory, may have multiple entries for a single
function. The FuncUnwinders rewrite includes the start of supporting
this correctly. In practice compact unwind encodings are used for
the entire range of the function today -- in fact, sometimes the same
encoding is used for multiple functions that have the same unwind
rules. But I want to handle a single function that has multiple
different compact unwind UnwindPlans eventually.

Reapply "Change -save-temps to emit unoptimized bitcode files."
This reapplies r224503 along with a fix for compiling Fortran by having the
clang driver invoke gcc (see r224546, where it was reverted). I have added
a testcase for that as well.
Original commit message:
It is often convenient to use -save-temps to collect the intermediate
results of a compilation, e.g., when triaging a bug report. Besides the
temporary files for preprocessed source and assembly code, this adds the
unoptimized bitcode files as well.
This adds a new BackendJobAction, which is mostly mechanical, to run after
the CompileJobAction. When not using -save-temps, the BackendJobAction is
combined into one job with the CompileJobAction, similar to the way the
integrated assembler is handled. I've implemented this entirely as a
driver change, so under the hood, it is just using -disable-llvm-optzns
to get the unoptimized bitcode.

This allows the user to specify where to find the lit.site.cfg file two different ways:
* lit_site_config lit parameter
* LIT_SITE_CONFIG enviroment variable.
example usage:
```
lit -sv --param=libcxx_site_config=path/to/libcxx-build/test/lit.site.cfg path/to/tests
```
Or
```
export LIBCXX_SITE_CONFIG=path/to/libcxx-build/test/lit.site.cfg
lit -sv path/to/tests
```
The command line parameter will override the environment variable.
If neither options are present a warning is issued and the `lit.cfg` file is loaded directly.

Consider a template class with attributes on a method, and an explicit
specialization of that method:
template <int>
struct A {
void foo() final;
};
template <>
void A<0>::foo() {}
In this example, the attribute is `final`, but it might also be an
__attribute__((visibility("foo"))), noreturn, inline, etc. clang's current
behavior is to strip all attributes, which for some attributes is wrong
(the snippet above allows a subclass of A<0> to override the final method, for
example) and for others disagrees with gcc.
So stop dropping attributes. r95845 added this code without a test case, and
r176728 added the code for dropping attributes on parameters (with tests, but
they still pass).

these two attributes work. (This is covered by existing tests.)

TestCompletion was broken for Ubuntu (and probably for Debian also).
The issue was that the lldb prompt in color (which is the default
behavior) was confusing pexpect.

[LIT] Add JSONMetricValue type to wrap types supported by the json encoder.
Summary:
The following types can be encoded and decoded by the json library:
`dict`, `list`, `tuple`, `str`, `unicode`, `int`, `long`, `float`, `bool`, `NoneType`.
`JSONMetricValue` can be constructed with any of these types, and used as part of Test.Result.
This patch also adds a toMetricValue function that converts a value into a MetricValue.

Add the ExceptionHandling::MSVC enumeration
It is intended to be used for a family of personality functions that
have similar IR preparation requirements. Typically when interoperating
with MSVC personality functions, bits of functionality need to be
outlined from the main function into helper functions. There is also
usually more than one landing pad per invoke, which does not match the
LLVM IR landingpad representation.
None of this is implemented yet. This change just adds a new enum that
is active for *-windows-msvc and delegates to the EH removal preparation
pass. No functionality change for other targets.

[libcxx] Allow the use of ccache when running the test suite.
Summary:
In order to get the bots running quicker I would like to be able to use ccache
with the test suite. This patch adds support for running the test suite using
ccache. To use ccache pass `--param=use_ccache=true` when running the test suite.
ccache will not cache any command that invokes ld, so the build step needs to be
split into two separate compile commands. The cost of splitting the build step
into two parts when not using ccache seems to be minimal. On my machine I saw a
difference of ~5 seconds on a 5 minute test suite run.
A full test suite run with ccache generates about 250MB of cached data.
I recorded the following times for running the test suite in the following configurations:
- no ccache: 340s
- initial ccache run: 380s
- rerun with ccache (no changes): 53s.
- rerun with ccache (<string> changed): 80s
- rerun with ccache (<cmath> changed): 169s
- rerun with ccache (<valarray> changed): 69s

[ASan] Restrict the set of flags overriden at activation.
Summary:
Change the way ASan flag parsing is performed at activation: instead
of overwriting all ASan and common flags from the activation string,
ASan will now only override a handful of whitelisted flags.
This is a first step towards making runtime flags immutable after
initialization. I plan to re-factor the activation stragegy to
the following one:
- Parse commandline flags. Override the defaults from compile
definition, env var, etc. Flags are immutable at this point.
- Initiailize the runtime from commandline flags.
- If ASan needs to be started deactivated, stash the runtime
state in "asan_deactivated_flags" and deactivate the runtime.
- When ASan is activated, override "asan_deactivated_flags" with
activation flags, and use it to re-activate the runtime.
