  Log Message:
  -----------
  Revert2 "[DebugInfo][DWARF] Set is_stmt on first non-line-0 instruction in BB (#105524)"

Reverted due to large .debug_line size regressions for some
configurations; work currently in place to improve the output of this
behaviour in PR #108251.

This patch also modifies two tests that were created or modified after
the original commit landed and are affected by the revert:

  llvm/test/CodeGen/X86/pseudo_cmov_lower2.ll
  llvm/test/DebugInfo/X86/empty-line-info.ll

This reverts commit 5fef40c2c477e92187bd4e5c18091eca6b8465cc.
