We weren't modifying the lock set when intersecting with one coming
from a break-terminated block. This is inconsistent, since break isn't a
back edge, and it leads to false negatives with scoped locks. We usually
don't warn for those when joining locksets aren't the same, we just
silently remove locks that are not in the intersection. But not warning
and not removing them isn't right.

The motivation here is to make it available in the base class whether a
fact is managed or not. That would have meant three flags on the base
class, so I had a look whether we really have 8 possible combinations.
It turns out we don't: asserted and declared are obviously mutually
exclusive. Managed facts are only created when we acquire a capability
through a scoped capability. Adopting an asserted or declared lock will
not (in fact can not, because Facts are immutable) make them managed.
We probably don't want to allow adopting an asserted lock (because then
the function should probably have a release attribute, and then the
assertion is pointless), but we might at some point decide to replace a
declared fact on adoption.

MSVC has added some new flags. Although they're not supported, this adds
parsing support for them so clang-cl doesn't treat them as filenames.
Except for /fsanitize=address which we do support. (clang-cl already
exposes the -fsanitize= option, but this allows using the
MSVC-spelling with a slash.)

AMDGPU backend need to know whether floating point opcodes that support exception
flag gathering quiet and propagate signaling NaN inputs per IEEE754-2008, which is
conveyed by a function attribute "amdgpu-ieee". "amdgpu-ieee"="false" turns this off.
Without this function attribute backend assumes it is on for compute functions.
-mamdgpu-ieee and -mno-amdgpu-ieee are added to Clang to control this function attribute.
By default it is on. -mno-amdgpu-ieee requires -fno-honor-nans or equivalent.

Currently Clang does not add mustprogress to inifinite loops with a
known constant condition, matching C11 behavior. The forward progress
guarantee in C++11 and later should allow us to add mustprogress to any
loop (http://eel.is/c++draft/intro.progress#1).
This allows us to simplify the code dealing with adding mustprogress a
bit.

Previously, the JavaScript import sorter would ignore `// clang-format
off` and `on` comments. This change fixes that. It tracks whether
formatting is enabled for a stretch of imports, and then only sorts and
merges the imports where formatting is enabled, in individual chunks.
This means that there's no meaningful total order when module references are mixed
with blocks that have formatting disabled. The alternative approach
would have been to sort all imports that have formatting enabled in one
group. However that raises the question where to insert the
formatting-off block, which can also impact symbol visibility (in
particular for exports). In practice, sorting in chunks probably isn't a
big problem.
This change also simplifies the general algorithm: instead of tracking
indices separately and sorting them, it just sorts the vector of module
references. And instead of attempting to do fine grained tracking of
whether the code changed order, it just prints out the module references
text, and compares that to the previous text. Given that source files
typically have dozens, but not even hundreds of imports, the performance
impact seems negligible.
