It doesn't make sense to me why these bots are failing as the
traceback does not agree with the source code. It's possible
something is stale or there is some other mysterious error,
but in any case hopefully this fixes it.

This was a bug in the test that was only exposed as a result of
refactoring some code in lit configuration files. Previously,
llvm's lit configuration would only set the target-windows feature
if the system was also windows. Since cross-compilation is
a thing, this isn't correct. target-windows should be set
independently of system-windows.
Adding to that bug, this particular test then checked for
target-windows when it really meant "can I call a certain API on
the host machine", which is what system-windows is for.
Ultimately, this test only works if *both* the target and host
are Windows, so I've updated the test to reflect that.

The same code appears earlier in the function. This represents an earlier version of what became r313373 that I still had sitting in my local repo.

Summary:
For a lot of older CPUs we have a 1:1 mapping between CPU name and enum name. But many of them are effectively aliases of each other and as a result are always repeated together at every usage
This patch removes most of the duplication. It also uses StringSwitch::Cases to make the many to one mapping in the StringSwitch more obvious.

A few tests were manually constructing a LitConfig object, since
I added a new argument to it this was triggering some failures
I didn't detect. `ninja check-lit` passes now.

This is helpful for debugging test failures since it removes
the multiprocessing pool from the picture. This will obviously
slow down the test suite by a few orders of magnitude, so it
should only be used for debugging specific failures.

readelf tool reports an error when output contains the same section
in multiple COMDAT groups. That can be useful.
Path teaches llvm-readobj to do the same.

This allows vector-sized store merging of constants in DAGCombiner using the existing code in MergeConsecutiveStores().
All of the twisted logic that decides exactly what vector operations are legal and fast for each particular CPU are
handled separately in there using the appropriate hooks.
For the motivating tests in merge-store-constants.ll, we already produce the same vector code in IR via the SLP vectorizer.
So this is just providing a backend backstop for code that doesn't go through that pass (-O1). More details in PR24449:
https://bugs.llvm.org/show_bug.cgi?id=24449 (this change should be the last step to resolve that bug)

We just need to toggle bits 1 and 5 of the immediate and swap the sources. The peephole pass could trigger commuting/folding for this later, but its easy enough to fix in isel.
Disable the peephole pass on the main vperm2x128 test so we know we're doing this through isel.

I've moved the test cases from the InstCombine optimizations to the backend to keep the coverage we had there. It covered every possible immediate so I've preserved the resulting shuffle mask for each of those immediates.

OpenOCD sends register classes as two separate <feature> nodes, fixed parser to process both of them.
OpenOCD returns "l" in response to "qfThreadInfo", so IsUnsupportedResponse() was false and we were ending up without any threads in the process. I think it's reasonable to assume that there's always at least one thread.

I'm going to autoupgrade these intrinsics in a future commit. This bit will never be set in the resulting output so pre-removing the bit.

This reverts commit 6389e7aa724ea7671d096f4770f016c3d86b0d54.
There is a bug in this implementation where the string value of the
checksum is outputted, instead of the actual hex bytes. Therefore the
checksum is incorrect, and this prevent pdbs from being loaded by visual
studio. Revert this until the checksum is emitted correctly.

Summary:
Restore the `__builtin_wasm_rethrow` builtin deleted in D37931. On second
thought, it appears it can be used to implement `__cxa_rethrow`.

It looks like this is going to be non-trivial to get working
in both Py2 and Py3, so for now I'm reverting until I have time
to fully test it under Python 3.
