e7547b25 - [KeyInstr][DwarfDebug] Add is_stmt emission support (#133495)

[KeyInstr][DwarfDebug] Add is_stmt emission support (#133495) Interpret Key Instructions metadata to determine is_stmt placement. The lowest rank (highest precedent) instructions in each {InlinedAt, atomGroup} set are candidates for is_stmt. Only the last instruction in each set in a given block gets is_stmt. Calls always get is_stmt. RFC: https://discourse.llvm.org/t/rfc-improving-is-stmt-placement-for-better-interactive-debugging/82668
