[SIL] Key consume addr checking off var_decl attr.

Browse Source 
Previously, the lexical attribute on allock_stack instructions was used.
This doesn't work for values without lexical lifetimes which are
consumed, e.g. stdlib CoW types.  Here, the new var_decl attribute on
alloc_stack is keyed off of instead.  This flag encodes exactly that a
value corresponds to a source-level VarDecl, which is the condition
under which checking needs to run.
