bd2a910a63 Ignore generated @import statements in the expression evaluator
Summary:
The ClangModulesDeclVendor is currently interpreting all injected `@import` statements in our expression
wrapper as modules that the user has explicitly requested to be persistently loaded. As we inject
`@import` statements with our std module prototype, the ClangModulesDeclVendor will start compiling
and loading unrelated C++ modules because it thinks the user has requested that it should load them. As
the ClangModulesDeclVendor is lacking the setup to compile these modules (e.g. it lacks the include paths),
it will then actually just fail to compile them and cause the whole expression evaluation to fail. This causes
these tests to fail on systems that enable the ClangModulesDeclVendor (such as macOS).

This patch fixes this by preventing the ClangModulesDeclVendor from interpreting `@import` statements
in the wrapper source code. This is done by check if the import happens in the fake source file containing
our wrapper code (which implies it was generated by LLDB).

This patch doesn't reenable the tests as there is more work needed to get the tests running on macOS (D67760)

bce849e350 [clang-format] NFC clang-format the clang-format unit tests
Summary:
It is annoying that the clang-format tests aren't themselves clang-formatted, if you use a format on save option in VS or vim this file gets massively changed then you have to `git difftool` all the other changes back out, which is risky.

I know people don't like mass clang-format changes but sometimes it becomes unmanageable to not. There are no other changes here other than just the reformat.

clang-format tests all pass.

```

clamp255 is a common operator in image processing, can be implemented
in a shifty way "(255 - X) >> 31 | X & 255". Fold shift into select
enables more optimization, e.g., vmin generation for ARM target.

2c5e6646ef [MemorySSA] Update Phi insertion.
Summary:
MemoryPhis may be needed following a Def insertion inthe IDF of all the
new accesses added (phis + potentially a def). Ensure this also  occurs when
only the new MemoryPhis are the defining accesses.

Note: The need for computing IDF here is because of new Phis added with
edges incoming from unreachable code, Phis that had previously been
simplified. The preferred solution is to not reintroduce such Phis.
This patch is the needed fix while working on the preferred solution.

When a cold path is outlined, the value tracking in the assumption cache may be
invalidated due to the code motion.  We would previously trip an assertion in
subsequent passes (but required the passes to happen in a single run as the
assumption cache is shared across the passes).  Invalidating the cache ensures
that we get the correct information when needed with the legacy pass manager as
well.

Summary:

https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md#load-and-splat.

DAGISel does not allow matching multiple copies of the same load in a

that should be splatted.

Depends on D67783.

948786c929 File::SetDescriptor() should require options
lvm_private::File::GetStream() can fail if m_options == 0

It's not clear from the header a File created with a descriptor will be
not be usable by many parts of LLDB unless SetOptions is also called,
but it is.

This is because those parts of LLDB rely on GetStream() to use the
file, and that in turn relies on calling fdopen on the descriptor. When
calling fdopen, GetStream relies on m_options to determine the access
mode. If m_options has never been set, GetStream() will fail.

This patch adds options as a required argument to File::SetDescriptor
and the corresponding constructor.
