53bfc767a3 SIL: Track target formal type for casts 
SIL type lowering erases DynamicSelfType, so we generate
incorrect code when casting to DynamicSelfType. Fixing this
requires a fair amount of plumbing, but most of the
changes are mechanical.

Note that the textual SIL syntax for casts has changed
slightly; the target type is now a formal type without a '$',
not a SIL type.

Also, the unconditional_checked_cast_value and
checked_cast_value_br instructions now take the _source_
formal type as well, just like the *_addr forms they are
intended to replace.

fd4828e40a Eliminate -assume-parsing-unqualified-ownership-sil from tests. 
I am doing this separately from the actual change to eliminate the option to
make it easier to review.

50e7c066f7 Parse: Simpler handling of 'class' in protocol inheritance list 
Instead of treating this as its own thing, just parse it as if
the user wrote 'AnyObject'.

551b94b7ae [rc-id] Make RCIdentity strip off single-pred arguments. 
This was already done in a few different places in the compiler. There is no
reason not to have it in RCIdentity directly.

2f3709443d [rc-id] Make RCIdentity strip off single-pred arguments. 
In a bunch of use-cases we use stripSinglePredecessorArgs to eliminate this
case. There is no reason to assume that this is being done in the caller of
RCIdentity. Lets make sure that we handle this case here.

80e5854e88 [codegardening] Add a new pass called RCIdentityDumper that dumps the RCIdentity of all values in all functions. 
This allows for the RCIdentityAnalysis to be tested independent of other
passes.

Also add some initial tests for RCIdentity. I am stepping through "strip by
strip" but I did not have time to finish the coverage.
