basic.ll:test_lifetime_bitcast is a strange case. The comment says
it's trying to keep the lifetime intrinsics for bitcasts. Leave a
dummy bitcast for now to keep it happy.

This was a painless conversion.

The plan is to intersect this list with the checks selected per config.
This is not yet done, but the initial list is checked in as a baseline.

It doesn't really make sense for the bfloat matmul to derive
from sve_bfloat_dot_base, especially since it's not used
anywhere else.

This revision exports `collapseGenericOpIterationDims` to a header so it can be used outside of the pattern.  We have use-case where we want to call this function directly.

Based on include-cleaner's version, but:

- remove assert that can fail for input `/\<newline>* */`
- assert was also checking the wrong condition: that the prefix *differed* from
  either `//` or from `/*`. Avoid use of strncmp where we can.
- add a comment that the brittleness of the text matching is intentional

This patch also implements not emit fence in atomic binary operation
when AtomicOrdering is monotonic and fixes the issue of loading from
non ptr parameters.

The processing of other levels of AtomicOrdering will be added later.

The Assignment Tracking debug-info feature is outlined in this RFC:

https://discourse.llvm.org/t/
rfc-assignment-tracking-a-better-way-of-specifying-variable-locations-in-ir

Split dbg.assign intrinsics into fragments similarly to what SROA already does
for dbg.declares, except that there's many more intrinsics to split. The
function migrateDebugInfo generates new dbg.assigns intrinsic for each part of
a split store.

ritht is initialized with either exact (if available) or
with constant max exit count. In the future, this can be improved.

Hypothetically this is not an NFC (it is possible that exact is not
known and max is known for a particular exit), but for how we use
it now it seems be an NFC (or at least I could not find an example
where it differs). constant max exit count. In the future, this can
be improved.

We can use `parseCommaSeparatedList` to simplify the logic of
`parseDynamicIndexList`. We don't need to explicitly check delimiters

Since opt no longer supports to run default (O0/O1/O2/O3/Os/Oz)

This reverts commit 1dc0a1e5.

Failures were caused by unintentional conversion to native slashes by
remove_dots, so undo that: we always suggest posix slashes for includes.

This could potentially be a change in behavior on windows if people were
spelling headers with backslashes and headermaps contained backslashes,
but that's all underspecified and I don't think anyone uses headermaps
on windows.
