when *reading* them back in, the code reads them as 32-bit values in

[CMake] Add compiler-rt header files to the list of sources for targets
when building with an IDE so that header files show up in the UI.
This massively improves the development workflow in IDEs.
To implement this a new function `compiler_rt_process_sources(...)` has
been added that adds header files to the list of sources when the
generator is an IDE. For non-IDE generators (e.g. Ninja/Makefile) no
changes are made to the list of source files.
The function can be passed a list of headers via the
`ADDITIONAL_HEADERS` argument. For each runtime library a list of
explicit header files has been added and passed via
`ADDITIONAL_HEADERS`. For `tsan` and `sanitizer_common` a list of
headers was already present but it was stale and has been updated
to reflect the current state of the source tree.
The original version of this patch used file globbing (`*.{h,inc,def}`)
to find the headers but the approach was changed due to this being a
CMake anti-pattern (if the list of headers changes CMake won't
automatically re-generate if globbing is used).
The LLVM repo contains a similar function named `llvm_process_sources()`
but we don't use it here for several reasons:
* It depends on the `LLVM_ENABLE_OPTION` cache variable which is
not set in standalone compiler-rt builds.
* We would have to `include(LLVMProcessSources)` which I'd like to
avoid because it would include a bunch of stuff we don't need.

With GCC, the same is achieved by using a custom spec file, but
since clang doesn't use spec files, we have to allow other means of
overriding what default libraries to use (without going all the
way to using -nostdlib, which would exclude everything). The same
approach, in detecting certain user specified libraries and omitting
others from the defaults, was already used in SVN r314138.

[PM/Unswitch] Fix a collection of closely related issues with trivial
switch unswitching.
The core problem was that the way we handled unswitching trivial exit
edges through the default successor of a switch. For some reason
I thought the right way to do this was to add a block containing
unreachable and point the default successor at this block. In
retrospect, this has an amazing number of problems.
The first issue is the one that this pass has always worked around -- we
have to *detect* such edges and avoid unswitching them again. This
seemed pretty easy really. You juts look for an edge to a block
containing unreachable. However, this pattern is woefully unsound. So
many things can break it. The amazing thing is that I found a test case
where *simple-loop-unswitch itself* breaks this! When we do
a *non-trivial* unswitch of a switch we will end up splitting this exit
edge. The result will be a default successor that is an exit and
terminates in ... a perfectly normal branch. So the first test case that
I started trying to fix is added to the nontrivial test cases. This is
a ridiculous example that did just amazing things previously. With just
unswitch, it would create 10+ copies of this stuff stamped out. But if
you combine it *just right* with a bunch of other passes (like
simplify-cfg, loop rotate, and some LICM) you can get it to do this
infinitely. Or at least, I never got it to finish. =[
This, in turn, uncovered another related issue. When we are manipulating
these switches after doing a trivial unswitch we never correctly updated
PHI nodes to reflect our edits. As soon as I started changing how these
edges were managed, it became obvious there were more issues that
I couldn't realistically leave unaddressed, so I wrote more test cases
around PHI updates here and ensured all of that works now.
And this, in turn, required some adjustment to how we collect and manage
the exit successor when it is the default successor. That showed a clear
bug where we failed to include it in our search for the outer-most loop
reached by an unswitched exit edge. This was actually already tested and
the test case didn't work. I (wrongly) thought that was due to SCEV
failing to analyze the switch. In fact, it was just a simple bug in the
code that skipped the default successor. While changing this, I handled
it correctly and have updated the test to reflect that we now get
precise SCEV analysis of trip counts for the outer loop in one of these
cases.

[XRay][compiler-rt] xray::Array Freelist and Iterator Updates
Summary:
We found a bug while working on a benchmark for the profiling mode which
manifests as a segmentation fault in the profiling handler's
implementation. This change adds unit tests which replicate the
issues in isolation.
We've tracked this down as a bug in the implementation of the Freelist
in the `xray::Array` type. This happens when we trim the array by a
number of elements, where we've been incorrectly assigning pointers for
the links in the freelist of chunk nodes. We've taken the chance to add
more debug-only assertions to the code path and allow us to verify these
assumptions in debug builds.
In the process, we also took the opportunity to use iterators to
implement both `front()` and `back()` which exposes a bug in the
iterator decrement operation. In particular, when we decrement past a
chunk size boundary, we end up moving too far back and reaching the
`SentinelChunk` prematurely.
This change unblocks us to allow for contributing the non-crashing
version of the benchmarks in the test-suite as well.
