    A llvm/test/Transforms/PGOProfile/chr_coro.ll

  Log Message:
  -----------
  [CHR] Skip region containing llvm.coro.id

When a block containing llvm.coro.id is cloned during CHR, it inserts an invalid
PHI node with token type to the beginning of the block containing llvm.coro.begin.
To avoid such case, we exclude regions with llvm.coro.id.
