[libcxxabi] Refactor building and testing libc++abi without threads
Summary:
This patch adds CMake support for building and testing libc++abi without threads.
1. Add `LIBCXXABI_ENABLE_THREADS` option to CMake.
2. Propagate `LIBCXXABI_ENABLE_THREADS` to lit via lit.site.cfg.in
3. Configure tests for `LIBCXXABI_ENABLE_THREADS=OFF
Currently the test suite does not work when libc++abi is built without threads because that information does not propagate to the test suite.

[libcxxabi] Refactor test timing logic and disable by default.
Summary:
When using LIT the timing output is entirely unused but introduces a dependency on `<chrono>`. When libc++ is built without a montonic clock this causes some of the tests to fail.
This patch factors out all of the timing logic into `support/timer.hpp` and disables it by default. To enable the timing you must define `LIBCXXABI_TIME_TESTS`.

Clarify wording in the LangRef around !invariant.load
Clarify the wording around !invariant.load to properly reflect the semantics of such loads with respect to control dependence and location lifetime. To the best of my knowledge, the revised wording respects the actual implementation and understanding of issues involved highlighted in the recent 'Optimization hints for "constant" loads' thread on LLVMDev.
In particular, I'm aiming for the following results:
- To clarify that an invariant.load can fault and must respect control dependence. In particular, it is not sound to unconditionally pull an invariant load out of a loop if that loop would potentially never execute.
- To clarify that the invariant nature of a given pointer does not preclude the modification of that location through a pointer which is unrelated to the load operand. In particular, initializing a location and then passing a pointer through an opaque intrinsic which produces a new unrelated pointer, should behave as expected provided that the intrinsic is memory dependent on the initializing store.
- To clarify that storing a value to an invariant location is defined. It can not, for example, be considered unreachable. The value stored can be assumed to be equal to the value of any previous (or following!) invariant load, but the store itself is defined.
I recommend that anyone interested in using !invariant.load, or optimizing for them, read over the discussion in the review thread. A number of motivating examples are discussed.

Add better support for custom test runners.
Summary:
I finally got around to merging the many, many changes to lit.cfg into
Android's libc++. This patch makes it simpler to actually use a custom
configuration and test format.
First, I've factored out _build, _run, and _clean methods from
_execute_test, since these are the likely parts that will need to be
overridden. This is likely a first step in the work jroelofs has been
doing with improving cross-compiling test execution.
Second, I've added a `configuration_variant` to the config. This
entry, if present, is a string that forms the prefix of the class that
is to be used to configure the test runner. For example, Android sets
`config.configuration_variant = 'Android'`, and this causes an object
of type `AndroidConfiguration` to be constructed.
As an example of how this will be used, see:

This patch delays the dereference adjustment until we are sure the thrown type is a pointer type. It is possible the thrown type is not a pointer and is smaller than `sizeof(void*)`.

I audited all the call sites of `can_catch(...)` and there are no places where `adjustedPtr` is used if `can_catch(...)` returns false. For this reason the patch should not introduce any functionality change.

This only supports pointer wrappers with a conversion to `bool` to check

Fixed an issue where a DW_FORM_ref{2,4,8} might be extracted incorrectly because the wrong compile unit was being used to calculate the compile unit relative offset.
This was fixed by making the DWARFFormValue contain the compile unit that it needs so it can decode its form value correctly. Any form value that requires a compile unit will now assert. If any of the assertions that were added are triggered, then code that led to the extraction of the form value without properly setting the compile unit must be fixed immediately.

UnwindLLDB::AddOneMoreFrame to try the fallback unwind plan on

In RegisterContextLLDB::TryFallbackUnwindPlan, when we're

This is the first step of making lldb able to create target-specific things
(e.g. breakpoints, stop-hooks) before we have any targets - for instance in
your ~/.lldbinit file. These will then get copied over to any new targets
that get created. So far, you can only make stop-hooks.
Breakpoints will have to learn to move themselves from target to target for
us to get them from no-target to new-target.
We should also make a command & SB API way to prime this ur-target.
