The other code all use the hasMinSize(), so I change the last two
hasFnAttribute(Attribute::MinSize).

DenseSet, SmallPtrSet, SmallSet, SetVector, and StringSet recently
gained C++23-style insert_range.  This patch replaces:

  Dest.insert(Src.begin(), Src.end());

with:

  Dest.insert_range(Src);

This patch does not touch custom begin like succ_begin for now.

Identified with misc-include-cleaner.

Hot cold splitting should not outline:
1. Basic blocks with token type instructions
1. Functions with scoped EH personality (As suggested by Vedant in
https://github.com/llvm/llvm-project/issues/40056#issuecomment-981009129)

Fixes: #40056

Currently, with hot cold splitting, when a cold region is identified, it
is added to the region list of ColdBlocks. Then when another cold region
(B) identified overlaps with a ColdBlocks region (A) already added to
the list, the region B is not added to the list because of the
overlapping with region A. The splitting analysis is performed, and the
region A may not get split, for example, if it’s considered too
expansive. This is to improve the handling the overlapping case when the
region A is not considered good for splitting, while the region B is
good for splitting.
 
The change is to move the cold region splitting analysis earlier to
allow more cold region splitting. If an identified region cannot be
split, it will not be added to the candidate list of ColdBlocks for
overlapping check.

The builtin_expect(), and C++20's likely, unlikely attributes assign branch_weights to annotated branches.

This patch adds the the ability to query branch !prof metadata and improve static analysis based on that.

Mostly removing includes of InitializePasses.h and Pass.h in
passes that no longer has support for the legacy PM.

These are part of the optimization pipeline, of which the legacy pass manager version is deprecated.

This patch adds !nosanitize metadata to FixedMetadataKinds.def, !nosanitize indicates that LLVM should not insert any sanitizer instrumentation.
