[MemProf] Control availability of hot/cold operator new from LTO link
Adds an LTO option to indicate that whether we are linking with an
allocator that supports hot/cold operator new interfaces. If not,
at the start of the LTO backends any existing memprof hot/cold
attributes are removed from the IR, and we also remove memprof metadata
so that post-LTO inlining doesn't add any new attributes.
This is done via setting a new flag in the module summary index. It is
important to communicate via the index to the LTO backends so that
distributed ThinLTO handles this correctly, as they are invoked by
separate clang processes and the combined index is how we communicate
information from the LTO link. Specifically, for distributed ThinLTO the
LTO related processes look like:
```
# Thin link:
$ lld --thinlto-index-only obj1.o ... objN.o -llib ...
# ThinLTO backends:
$ clang -x ir obj1.o -fthinlto-index=obj1.o.thinlto.bc -c -O2
...
$ clang -x ir objN.o -fthinlto-index=objN.o.thinlto.bc -c -O2
```
It is during the thin link (lld --thinlto-index-only) that we have
visibility into linker dependences and want to be able to pass the new
option via -Wl,-supports-hot-cold-new. This will be recorded in the
summary indexes created for the distributed backend processes
(*.thinlto.bc) and queried from there, so that we don't need to know
during those individual clang backends what allocation library was
linked. Since in-process ThinLTO and regular LTO also use a combined
index, for consistency we query the flag out of the index in all LTO
backends.
Additionally, when the LTO option is disabled, exit early from the
MemProfContextDisambiguation handling performed during LTO, as this is
unnecessary.
Depends on D149117 and D149192.

where '__rcu' is a macro expanding to '__attribute__((btf_type_tag("rcu")))'.
Let us print btf_type_tag properly in clang so bcc tools and broader type printing

[SCEV][reland] More precise trip multiples
We currently have getMinTrailingZeros(), from which we can get a SCEV's
multiple by computing 1 << MinTrailingZeroes. However, this only gets us
multiples that are a power of 2. This patch introduces a way to get max
constant multiples that are not just a power of 2. The logic is similar
to that of getMinTrailingZeros. getMinTrailingZerosImpl is replaced by
computing the max constant multiple, and counting the number of trailing
bits.
I have so far found this useful in two places:
1) Computing unsigned constant ranges. For example, if we have i8
{10,+,10}<nuw>, we know the max constant it can be is 250.
2) My original intent was to use this in getSmallConstantTripMultiples,
but it has no effect right now due to change from D110587. For
example, if we have backedge count `(6 * %N) - 1`, the trip count
becomes `1 + zext((6 * %N) - 1)`, and we cannot say that 6 is a
multiple of the SCEV. I plan to look further into this separately.
The implementation assumes the value is unsigned. It can probably be
extended to handle signed values as well.
If the code sees that a SCEV does not have <nuw>, it will fall back to
finding the max multiple that is a power of 2. Multiples that are a
power of 2 will still be a multiple even after the SCEV overflows. This
does not apply to other values. This is the 1st commit message:
---
This relands https://reviews.llvm.org/D141823. The verification fails
when expensive checks are turned on. This can occur when:
1. SCEV S's multiple is cached
2. SCEV S's no wrap flags are strengthened, and the multiple changes
3. SCEV verifier finds that S's cached and recomputed multiple are
different
We eliminate most cases by forgetting SCEVAddRecExpr's cached values
when the flags are modified, but there are still cases for other SCEV
types. We relax the check by making sure the cached multiple divides the
recomputed multiple, ensuring the cached multiple is correct,
conservative multiple.
