Erik Eckstein 2ac69f3c55 SILCombine: fix propagation of concrete existentials in enums
This peephole optimization didn't consider that an alloc_stack of an enum can be overridden by another value.
The fix is to remove this peephole optimization at all because it is already covered by `optimizeEnum` in alloc_stack simplification.

Fixes a miscompile
