  -----------
  [IR][Core][NFC] Drop some BranchInst uses (#186352)

Now that CondBrInst and UncondBrInst are explicit subclasses, use them
instead.

HotColdSplitting was trying to inspect prof metadata also on
unconditional branches, fix this.

Also introduce C API cast functions and deprecate LLVMIsConditional in
favor of LLVMIsACondBrInst.

This patch covers all LLVM uses outside of Transforms, Analysis,
CodeGen/Target, SandboxIR, Frontend/OpenMP, tools, examples.
