block with a blockaddress still referring to it' replace the invalid 
blockaddress with a new blockaddress(@func, null) instead of a 
inttoptr(1).

This changes the bitcode encoding format, and still needs codegen 
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

parameters and template type parameters, which occurs when
substituting into the declarations of member templates inside class
templates. This eliminates errors about our inability to "reduce
non-type template parameter depth", fixing PR5311.

Also fixes a bug when instantiating a template type parameter
declaration in a member template, where we weren't properly reducing
the template parameter's depth.
