Tilmann Scheller 7cd0201f02 [ARM] Add earlyclobber constraint to pre/post-indexed ARM STR instructions.
The post-indexed instructions were missing the constraint, causing unpredictable STR instructions to be emitted.

The earlyclobber constraint on the pre-indexed STR instructions is not strictly necessary, as the instruction selection for pre-indexed STR instructions goes through an additional layer of pseudo instructions which have the constraint defined, however it doesn't hurt to specify the constraint directly on the pre-indexed instructions as well, since at some point someone might create instances of them programmatically and then the constraint is definitely needed.

This fixes PR20323.
