this patch - https://reviews.llvm.org/D110337 changes the way how hostcall
hidden argument is emitted for printf, but the sanitized kernels also use
hostcall buffer to report a error for invalid memory access, which is not
handled by the above patch and it leads to vdi runtime error:

80072fde61 [CUDA][HIP] Allow comdat for kernels
Two identical instantiations of a template function can be emitted by two TU's
with linkonce_odr linkage without causing duplicate symbols in linker. MSVC
also requires these symbols be in comdat sections. Linux does not require
the symbols in comdat sections to be merged by linker but by default
clang puts them in comdat sections.

If a template kernel is instantiated identically in two TU's. MSVC requires
that them to be in comdat sections, otherwise MSVC linker will diagnose them as
duplicate symbols. However, currently clang does not put instantiated template
kernels in comdat sections, which causes link error for MSVC.

This patch allows putting instantiated template kernels into comdat sections.

When folding and/or of icmps, look through add of a constant and
adjust the icmp range instead. Effectively, this decomposes
X + C1 < C2 style range checks back into a normal range. This allows

of this (or of range check and eq, and only one one side!) while
this handles it in fully generality.

This models lowering to `vpermd`/`vpermq`/`vpermps`/`vpermpd`,
that take a single input vector and a single index vector,
and are cross-lane. So far i haven't seen evidence that
replication ever results in demanding more than a single

```
INLINE inline_nest_level call_site_line call_site_file_num origin_num [address size]+

`INLNIE_ORIGIN` is simply a string pool for INLINE so that we won't have
duplicated names for inlined functions and can show up anywhere in the symbol
file.
`INLINE` follows immediately after `FUNC` represents the ranges of momery
address that has functions inlined inside the function.

bbef51eb43 [lldb] make it easier to find LLDB's python
It is surprisingly difficult to write a simple python script that
can reliably `import lldb` without failing, or crashing.   I'm
currently resorting to convolutions like this:

    def find_lldb(may_reexec=False):
		if prefix := os.environ.get('LLDB_PYTHON_PREFIX'):
			if os.path.realpath(prefix) != os.path.realpath(sys.prefix):
				raise Exception("cannot import lldb.\n"
					f"  sys.prefix should be: {prefix}\n"
					f"  but it is: {sys.prefix}")
		else:
			line1, line2 = subprocess.run(
				['lldb', '-x', '-b', '-o', 'script print(sys.prefix)'],
				encoding='utf8', stdout=subprocess.PIPE,
				check=True).stdout.strip().splitlines()
			assert line1.strip() == '(lldb) script print(sys.prefix)'
			prefix = line2.strip()
			os.environ['LLDB_PYTHON_PREFIX'] = prefix

		if sys.prefix != prefix:
			if not may_reexec:
				raise Exception(
					"cannot import lldb.\n" +
					f"  This python, at {sys.prefix}\n"
					f"  does not math LLDB's python at {prefix}")
			os.environ['LLDB_PYTHON_PREFIX'] = prefix
			python_exe = os.path.join(prefix, 'bin', 'python3')
			os.execl(python_exe, python_exe, *sys.argv)

		lldb_path = subprocess.run(['lldb', '-P'],
			check=True, stdout=subprocess.PIPE,
				encoding='utf8').stdout.strip()

		sys.path = [lldb_path] + sys.path

This patch aims to replace all that with:

  #!/usr/bin/env lldb-python
  import lldb
  ...

... by adding the following features:

* new command line option: --print-script-interpreter-info.  This
   prints language-specific information about the script interpreter
   in JSON format.

* new tool (unix only): lldb-python which finds python and exec's it.

48bb5f4cbe [clang] Add early exit when checking for const init of arrays.
Before this commit, on code like:

  struct S { ... };
  S arr[10000000];

while checking if arr is constexpr, clang would reserve memory for
arr before running constructor for S. If S turned out to not have a
valid constexpr c-tor, clang would still try to initialize each element
(and, in case the c-tor was trivial, even skipping the constexpr step
limit), only to discard that whole APValue later, since the first
element generated a diagnostic.

With this change, we start by allocating just 1 element in the array to
try out the c-tor and take an early exit if any diagnostics are
generated, avoiding possibly large memory allocation and a lot of work
initializing to-be-discarded APValues.

Fixes 51712 and 51843.

In the future we may want to be smarter about large possibly-constexrp
arrays and maybe make the allocation lazy.

e64c76672f [mlir] recursively convert builtin types to LLVM when possible
Given that LLVM dialect types may now optionally contain types from other
dialects, which itself is motivated by dialect interoperability and progressive
lowering, the conversion should no longer assume that the outermost LLVM
dialect type can be left as is. Instead, it should inspect the types it
contains and attempt to convert them to the LLVM dialect. Introduce this
capability for LLVM array, pointer and structure types. Only literal structures
are currently supported as handling identified structures requires the
converison infrastructure to have a mechanism for avoiding infite recursion in
case of recursive types.
