If tsan runtime will try to allocate something during exit handling,
the allocation will fail because there is no VA whatsoever.
It's observed to fail with the following error in some cases:
failed to allocate 0x1000 (4096) bytes of DTLS_NextBlock.
So terminate the process immediately.

LLDB does not like to import Python files with dashes or dots in their

are allowed for subpackages but not in module names. This patch improves
the user experience by printing a useful error.
Before this patch:
error: module importing failed: SyntaxError('invalid syntax',

...this pattern shows up in library code.
There are several potential generalizations as noted,
but we need to be careful that we get FP special-values
right, and it's not clear how much variation we should
expect to see from this exact idiom.
Also add a script for sysroot management. For now, it can only create
fake sysroots that just symlink to local folders. This is useful for

This came up during the review of D96817 because those deleted overloads force
the caller to explicitly create a StringRef when passing a string literal.
It seems they were added as some kind of help while migrating the code base to
StringRef in D24847, but I don't think they have any use these days and make
these functions awkward to use.
This patch just removes all the deleted overloads.

This is not perfect, and it might not work for opening files across

The PrepareForLTO stage of LoopRotate tries to avoid unrolling loops
with calls that might be inlined later. See D94232 where this was
introduced.
We didn't catch all occurances of the LoopRotatePass in the New Pass

manager switch.

Fold shuffle(bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d))) -> bop(shuffle(x,y),shuffle(z,w)),bop(shuffle(a,b),shuffle(c,d))
Attempt to fold from a shuffle of a pair of binops to a binop of shuffles, as long as one/both of the binop sources are also shuffles that can be merged with the outer shuffle. This should guarantee that we remove one binop without introducing any additional shuffles.
Technically there's potential for a merged shuffle's lowering to be poorer than the original shuffle, but it could also be better, and I'm not seeing any regressions as long as we keep the 'don't merge splats' rule already present in MergeInnerShuffle.
This expands and generalizes an existing X86 combine and attempts to merge either of each binop's sources (with an on-the-fly commutation of the shuffle mask) - we couldn't do that in the x86 version as it had to stay in a form that DAGCombine's MergeInnerShuffle would still recognise.
Fixes issue raised by @saugustine in rG5aa8f4c0843a where we were failing to replace null shuffle operands from MergeInnerShuffle to UNDEFs.

Some test systems do not use lit for test discovery but only for its
substitution and test selection because they use another way of managing
test collections, e.g. CTest. This forces those tests to be invoked with
lit --no-indirectly-run-check. When a mix of lit version is in use, it
requires to detect the availability of that option.
This commit provides a new config option standalone_tests to signal a
directory made of tests meant to run as standalone. When this option is
set, lit skips test discovery and the indirectly run check. It also adds
the missing documentation for --no-indirectly-run-check.
