ed623d7b64 [NFC] Shortened SIL [init] flag.

everywhere.

f7296ed903 SIL: fix bugs in the MemBehavior cache invalidation mechanism. 
When a non-value instruction (e.g. a destroy_addr) was deleted, the corresponding cache entry in MemoryBehaviorCache was not invalidated.
If a new instruction was allocated at the same memory location, the old - and invalid - cache entry was re-used.

This bug triggered a SIL memory lifetime failure in TempRValueElimination.

rdar://problem/72614608

This change also fixes another problem (which I found by inspection): Individual result values of MultipleValueInstructions were not invalidated correctly.
