Also fix a bug in the refactoring/rewrite of the x86 assembly
instruction profiler where I'd hard coded it as a 64-bit disassembler
instead of using the ArchSpec to pick a 32-bit or 64-bit disassembler
from llvm. When the disassembler would hit an instruction
that is invalid in 64-bit mode, it would stop disassembling the function.
This likely led to the TestSBData testsuite failure on linux with 32-bit

test infra: clear file-charged issues on rerun of file
This change addresses the corner case bug in the test
infrastructure where a test file times out *outside*
of any running test method. In those cases, the issue
was charged to the file, not to a test method within
the file. When that file is re-run successfully,
none of the test-method-level successes would clear
the file-level issue.
This change fixes that: for all test files that are
getting rerun (whether by being marked flaky or
via the --rerun-all-issues flag), file-level test
issues are searched for in each of those files. Each
file-level issue found in the rerun file list then
gets cleared.
A test of this feature is added to issue_verification,
using the technique there of moving the *.py.park file
to *.py to do an end-to-end validation.
This change also adds a .gitignore entry for pyenv
project-level files and fixes up a few minor pep8
formatting violations in files I touched.

function is a special member function before the class is instantiated. Only
these special member functions can be defaulted. In some cases, knowing

I'd said that nvcc doesn't allow you to add __host__ or __device__

[CUDA] Emit a warning if a CUDA host/device/global attribute is placed after '(...)'.
Summary:
This is probably the sane place for the attribute to go, but nvcc
specifically rejects it. Other GNU-style attributes are allowed in this
position (although judging from the warning it emits for
host/device/global, those attributes are applied to the lambda's
anonymous struct, not to the function itself).
It would be nice to have a FixIt message here, but doing so, or even
just getting the correct range for the attribute, including its '((' and
'))'s, is apparently Hard.

[MS] Implement __iso_volatile loads/stores as builtins
These are supposed to produce the same as normal volatile
pointer loads/stores. When -volatile:ms is specified,
normal volatile pointers are forced to have atomic semantics
(as is the default on x86 in MSVC mode). In that case,
these builtins should still produce non-atomic volatile
loads/stores without acquire/release semantics, which
the new test verifies.
These are only available on ARM (and on AArch64,
although clang doesn't support AArch64/Windows yet).
This implements what is missing for PR30394, making it possible
to compile C++ for ARM in MSVC mode with MSVC headers.

cmake: Install the OCaml libraries into a more correct path
Add a OCAML_INSTALL_PATH variable that can be used to control
the install path for OCaml libraries. The new variable defaults to
${OCAML_STDLIB_PATH}, i.e. the OCaml library path obtained from
the OCaml compiler. Install libraries into "llvm" subdirectory.
This fixes two issues:
1. OCaml library directories differ between systems, and 'lib/ocaml' is
incorrect e.g. on amd64 Gentoo where OCaml is installed
in 'lib64/ocaml'. Therefore, obtain the library path from the OCaml
compiler using 'ocamlc -where' (which is already used to set
OCAML_STDLIB_PATH), which is the method used commonly in OCaml packages.
2. The top-level directory is reserved for the standard library, and has
precedence over local directory in search path. As a result, OCaml
preferred the files installed along with previous LLVM version over the
source tree when building a new version, resulting in two versions being
mixed during the build. The new layout is used commonly by other OCaml
packages, and findlib is able to find the LLVM libraries successfully.
