[Codegen, BasicBlockSections] Avoid cloning blocks which have their machine block address taken. (#94296)
These blocks usually show up in the form of branches within inline
assembly. Since it's hard to rewire them, we fully omit paths with such
blocks from path cloning.

[BasicBlockSections] Apply path cloning with -basic-block-sections. (#68860)
https://github.com/llvm/llvm-project/commit/28b912687900bc0a67cd61c374fce296b09963c4
introduced the path cloning format in the basic-block-sections profile.
This PR validates and applies path clonings.
A path cloning is valid if all of these conditions hold:
1. All bb ids in the path are mapped to existing blocks.
2. Each two consecutive bb ids in the path have a successor relationship
in the CFG.
3. The path does not include a block with indirect branches, except
possibly as the last block.
Applying a path cloning involves cloning all blocks in the path (except
the first one) and setting up their branches.
Once all clonings are applied, the cluster information is used to guide
block layout in the modified function.
