The majority of all `addVisitor` callers follow the same pattern:
addVisitor(std::make_unique<SomeVisitor>(arg1, arg2, ...));
This patches introduces additional overload for `addVisitor` to simplify
that pattern:
addVisitor<SomeVisitor>(arg1, arg2, ...);

Since D100581, Clang started flagging this variable which is set but
never read. Based on comparing this function with __match_at_start_posix_nosubs
(which is very similar), I am pretty confident that `__j` was simply left
behind as an oversight in Howard's 6afe8b0a23.
Also workaround some unused variable warnings in the <random> tests.
It's pretty lame that we're not asserting the skew and kurtosis of
the binomial and negative binomial distributions, but that should be
tackled separately.

Introduces a test pass that rewrites PadTensorOps with static shapes as a sequence of:
```
linalg.init_tensor // to create output
linalg.fill // to initialize with padding value
linalg.generic // to copy the original contents to the padded tensor
```
The pass can be triggered with:
- `--test-linalg-transform-patterns="test-transform-pad-tensor"`

In such cases, the executables are not in the llvm_tools_dir directory, so we need to look in the other search locations. Previously, they were found via the PATH, but this was disabled by default in commit rGa1e6565.

This patch addresses an issue in which fixed-length (VLS) vector RVV
code could fail to reserve an emergency spill slot for their frame index
elimination. This is because we were previously only reserving a spill
slot when there were `scalable-vector` frame indices being used.
However, fixed-length codegen uses regular-type frame indices if it
needs to spill.
This patch does the fairly brute-force method of checking ahead of time
whether the function contains any RVV spill instructions, in which case
it reserves one slot. Note that the second RVV slot is still only
reserved for `scalable-vector` frame indices.
This unfortunately causes quite a bit of churn in existing tests, where
we chop and change stack offsets for spill slots.

The `DAGTypeLegalizer::WidenVSELECTMask` function is not (yet) ready for
scalable vector types, and has numerous places in which it tries to grab
either the fixed size or number of elements of its types.
I believe that it should be possible to update this method to properly
account for scalable-vector types, but we don't have test cases for
that; RISC-V bails out early on as it has legal i1 vector masks. As
such, this patch just prevents it from crashing.

Summary:
suggestPathToFileForDiagnostics is actively used in clangd for converting
an absolute path to a header file to a header name as it should be spelled
in the sources. Current approach converts absolute path to relative path.
This diff implements missing logic that makes a reverse lookup from the
relative path to the key in the header map that should be used in the sources.

incorrect std::string use. (Also remove redundant call to
RemoveFileOnSignal.)
Clang writes object files by first writing to a .tmp file and then
renaming to the final .obj name. On Windows, if a compile is killed
partway through the .tmp files don't get deleted.
Currently it seems like RemoveFileOnSignal takes care of deleting the
tmp files on Linux, but on Windows we need to call
setDeleteDisposition on tmp files so that they are deleted when
closed.
This patch switches to using TempFile to create the .tmp files we write
when creating object files, since it uses setDeleteDisposition on Windows.
This change applies to both Linux and Windows for consistency.

This reverts commit 20797b129f.
The linkage/visibility of `__profn_*` variables are derived
from the profiled functions.
extern_weak => linkonce
available_externally => linkonce_odr
internal => private
extern => private
_ => unchanged
The linkage/visibility of `__profc_*`/`__profd_*` variables are derived from
`__profn_*` with linkage/visibility wrestling for Windows.
The changes can be folded to the following without changing semantics.
```
if (TT.isOSBinFormatCOFF() && !NeedComdat) {
Linkage = GlobalValue::InternalLinkage;
Visibility = GlobalValue::DefaultVisibility;
}
```
That said, I think we can just delete the code block.
An extern/internal function will now use private `__profc_*`/`__profd_*`
variables, instead of internal ones. This saves some symbol table entries.
A non-comdat {linkonce,weak}_odr function will now use hidden external
`__profc_*`/`__profd_*` variables instead of internal ones. There is potential
object file size increase because such symbols need `/INCLUDE:` directives.
However such non-comdat functions are rare (note that non-comdat weak
definitions don't prevent duplicate definition error).
The behavior changes match ELF.

Coro-split functions with an active suspend point have their scope line set to
the line of the suspend point. However for compiler generated functions, this
results in debug info with unconventional results: a file named
`<compiler-generated>` with a non-zero line number. The convention for
`<compiler-generated>` is that the line number is zero.
This change propagates the scope line only for non-compiler generated
functions.

The PreInits of a loop transformation (atm moment only tile) include the computation of the trip count. The trip count is needed by any loop-associated directives that consumes the transformation-generated loop. Hence, we must ensure that the PreInits of consumed loop transformations are emitted with the consuming directive.
This is done by addinging the inner loop transformation's PreInits to the outer loop-directive's PreInits. The outer loop-directive will consume the de-sugared AST such that the inner PreInits are not emitted twice. The PreInits of a loop transformation are still emitted directly if its generated loop(s) are not associated with another loop-associated directive.
