We didn't properly build default argument expressions previously -- we
failed to build the wrapper CXXDefaultArgExpr node, which meant that
std::source_location misbehaved, and we didn't perform default argument
instantiation when necessary, which meant that dependent default
arguments in function templates didn't work at all.
Summary: Add a test to check if the standalone dialect is registered within standalone-opt. Similar to the mlir-opt commandline.mlir test.

https://reviews.llvm.org/D79246 introduces alignment propagation for vector transfer operations. Unfortunately, the alignment calculation is incorrect and can result in crashes.
This revision fixes the calculation by using the natural alignment of the memref elemental type, instead of the resulting vector type.
If more alignment is desired, it can be done in 2 ways:
1. use a proper vector.type_cast to transform a memref<axbxcxdxf32> into a memref<axbxvector<cxdxf32>> giving a natural alignment of vector<cxdxf32>
2. add an alignment attribute to vector transfer operations and propagate it.
With this change the alignment in the relevant tests goes down from 128 to 4.
Lastly, a few minor cleanups are performed and the custom `isMinorIdentityMap` is deprecated.

This linter has nothing to do with deopt, and the operands had clearly been copied blindly from another source. Rather than migrate to deopt operand bundle, let's just simplify the tests.
We've started (D80598) the process of migrating away from the inline operand lists in statepoints to using explicit operand bundles. Update a few tests to reflect the new preference. More to come, these were simply the ones outside any obvious grouping.
Summary:
This was attempted once before in https://reviews.llvm.org/D79698, but
was reverted due to the coverage pass running in the wrong part of the
pipeline. This commit puts it in the same place as the other sanitizers.
This changes PassBuilder.OptimizerLastEPCallbacks to work on a
ModulePassManager instead of a FunctionPassManager. That is because
SanitizerCoverage cannot (easily) be split into a module pass and a
function pass like some of the other sanitizers since in its current
implementation it conditionally inserts module constructors based on
whether or not it successfully modified functions.
This fixes compiler-rt/test/msan/coverage-levels.cpp under the new pass
manager (last check-msan test).

Summary:
We received a report of LiveDebugValues consuming 25GB+ of RAM when
compiling code generated by Unity's IL2CPP scripting backend.
There's an initial 5GB spike due to repeatedly copying cached lists of
MachineBasicBlocks within the UserValueScopes members of VarLocs.
But the larger scaling issue arises due to the fact that prior to range
extension, there are 81K basic blocks and 156K DBG_VALUEs: given enough
memory, LiveDebugValues would insert 101 million MIs (I counted this by
incrementing a counter inside of VarLoc::BuildDbgValue).
It seems like LiveDebugValues would have to be rearchitected to support
this kind of input (we'd need some new represntation for DBG_VALUEs that
get inserted into ~every block via flushPendingLocs). OTOH, large globs
of auto-generated code are typically not debugged interactively.
So: add cutoffs to disable range extension when the input is too big. I
chose the cutoffs experimentally, erring on the conservative side. When
compiling a large collection of Apple software, range extension never
got disabled.

Summary:
Verify that each DBG_VALUE has a debug location. This is required by
LiveDebugValues, and perhaps by other late passes.
There's an exception for tests: lots of tests use a two-operand form of
DBG_VALUE for convenience. There's no reason to prevent that.
This is an extension of D80665, but there's no dependency.

These are the two operand sets which are expected to survive more than another week or so. Instead of bothering to update the deopt and gc-transition operands, we'll just wait until those are removed and delete the code.
For those following along, this is likely to be the last (major) change in this sequence for about a week. I want to wait until all of this has been merged downstream to ensure I haven't introduced any bugs (and migrate some downstream code to the new interfaces). Once that's done, we should be able to delete Statepoint/ImmutableStatepoint without too much work.
The headers provided with recent GNU toolchains for PPC have code that includes
typedefs such as:
typedef _Complex float __cfloat128 __attribute__ ((__mode__ (__KC__)))
This patch allows clang to compile programs that contain
#include <math.h>
with -mfloat128 which it currently fails to compile.

We need to process only parameters. Allocas access can be calculated
afterwards.
Also don't create fake function for aliases and just resolve them on
initialization.
Jim pointed out that "every time somebody has touched the documentation
on startup files they have stated that we source the application one and
then the global one, even though in actual fact we’ve never done that."
Indeed, when we read the application specific .lldbinit file, the global
one is not read. This patch updates the man page to reflect that.
Summary:
* Test if the code sourcing the SyntaxTree compiles
* Output compiler errors and warnings to err
* Fix tests with code that did not compile

I'd apparently only grepped in the lib directories and missed a few used in the Statepoint header itself. Beyond simple mechanical cleanup, changed the type of one routine to reflect the fact it also returns a statepoint.
If this mask only clears bits in the low 32-bit half of a flat
pointer, these bits are always preserved in the result address
space. If the high bits are modified, they may need to be preserved
for some kind of user pointer tagging.
