Summary:
CoroSplit depends on CallGraphWrapperPass, but it was not explicitly adding it as a pass dependency.
This missing dependency can trigger errors / assertions / crashes in PMTopLevelManager::schedulePass() under certain configurations.

Some versions of the Visual C++ 2015 runtime have line tables with the
subsection kind of 0x800000F2. In cvinfo.h, 0x80000000 is documented to
be DEBUG_S_IGNORE. This appears to implement the intended behavior.

If the host uses 128 bit long doubles, the compiler should generate correct code for NVPTX devices. If the return type has 128 bit long doubles, in LLVM IR this type must be coerced to int array instead.

FP_ROUND defaults to Legal for all MVT types and nothing changes

The device code must use the same long double type as the host.
Otherwise the code cannot be linked and executed properly. Patch adds

- After `addrspacecast` is allowed to be eliminated in SROA, the
adjusting of storage pointer (from `alloca) needs to handle the
potential different address spaces between the storage pointer (from
alloca) and the pointer being used.

Implement the `xfer:libraries-svr4` packet by adding a new function that generates the list and then in Handle_xfer I generate the XML for it. The XML is really simple so I'm just using string concatenation because I believe it's more readable than having to deal with a DOM api.

Summary:
Fuchsia wants to use mutexes with PI in the Scudo code, as opposed to
our own implementation. This required making `lock` & `unlock` platform
specific (as opposed to `wait` & `wake`) [code courtesy of John
Grossman].
There is an additional flag required now for mappings as well:
`ZX_VM_ALLOW_FAULTS`.

Add `IsGP64bit` and `IsPTR64bit` to the list of `UnsupportedFeatures`
of the P5600 scheduling definitions. Also mark some MIPS 64-bit
instructions by PTR_64 and GPR_64 predicates. This reduces number
of "No schedule information for" and "lacks information for" errors
in case of marking this scheduler model as complete.
This patch is one of a series of patches. The goal is to make P5600
scheduler model complete and turn on the `CompleteModel` flag.

When running LLDB lit tests on Windows, the system selects a debug version
of Python, which was issuing lots of ResourceWarnings about files that
weren't closed. There are two kinds of them, and each test triggered one
of each.
This patch fixes one kind by ensuring TestRunner explicitly close the
temporary files created for routing stderr. This is important on Windows
but has no net effect on Posix systems.
The remaining ResourceWarnings are more elusive; the bug may lie in
the Python library subprocess.py, and it may be Windows-specific.

Before this patch, reproducers weren't relocatable. The reproducer
contained hard coded paths in the VFS mapping, as well in the yaml file
listing the different input files for the command interpreter. This
patch changes that:
- Use relative paths for the DataCollector.
- Use an overlay prefix for the FileCollector.

This includes saturating and non-saturating shifts, both with
immediate shift count and with the shift counts given by another
vector register; VSHLC (in which the bits shifted out of each active
vector lane are shifted in to the next active lane); and also VMOVL,
which is enough like an immediate shift that it didn't fit too badly
in this category.

Summary:
These form a small family of their own, to go with the floating-point
VMINNM/VMAXNM instructions added in a previous commit.
They introduce the first of many special cases in the mnemonic
recognition code, because VMIN with the E suffix used by the VPT
predication system needs to avoid being interpreted as the nonexistent
instruction 'VMI' with an ordinary 'NE' condition suffix.

Summary:
Their names began with a mishmash of `MVE_`, `t2` and no prefix at
all. Now they all start with `MVE_`, which seems like a reasonable
choice on the grounds that (a) NEON is the thing they're most at risk
of being confused with, and (b) MVE implies Thumb-2, so a prefix
indicating MVE is strictly more specific than one indicating Thumb-2.

This was found to be broken on Clang trunk. This is a revert of the
following commits (the subsequent commits added XFAILs to the tests
that were missing from the original submission):

r363014: Add some XFAILs
r363097: Add more XFAILs
r363197: Add even more XFAILs
llvm-svn: 363688
Summary:
When a function argument or return type is a homogeneous aggregate
which contains an FP16 vector but the target does not support FP16
operations natively, the type must be converted into an array of
integer vectors by then front end (otherwise LLVM will handle FP16
vectors incorrectly by scalarizing them and promoting FP16 to float,
see https://reviews.llvm.org/D50507).
Currently the logic for checking whether or not a given homogeneous
aggregate contains FP16 vectors is incorrect: it only looks at the
type of the first vector.
This patch fixes the issue by adding a new method
ARMABIInfo::containsAnyFP16Vectors and using it. The traversal logic
of this method is largely the same as in
ABIInfo::isHomogeneousAggregate.

1) `-x foo` currently dumps one `foo`. This change makes it dump all `foo`.
2) `-x foo -x foo` currently dumps `foo` twice. This change makes it dump `foo` once.
In addition, if foo has section index 9, `-x foo -x 9` dumps `foo` once.
3) Give a warning instead of an error if `foo` does not exist.
The new behaviors match GNU readelf.
Also, print a new line as a separator between two section dumps.
GNU readelf uses two lines, but one seems good enough.

Summary:
This introduces a few new concepts:
- tweaks have an Intent (they don't all advertise as refactorings)
- tweaks may produce messages (for ShowMessage notification). Generalized
Replacements -> Effect.
- tweaks (and other features) may be hidden (clangd -hidden-features flag).
We may choose to promote these one day. I'm not sure they're worth their own
feature flags though.
Verified it in vim-clangd (not yet open source), curious if the UI is ok in VSCode.
