  Add Fix*Address methods to Process, call into ABI

We need to clear non-addressable bits from addresses across
the lldb sources.  Currently these need to use an ABI method
to clear those bits from addresses, which you do by taking a
Process, getting the current ABI, then calling the method.

Simplify this by providing methods in Process which call into
the ABI methods themselves.

  Log Message:
  -----------
  Clear non-addressable bits from pc/fp/sp in unwinds

Some Darwin corefiles can have the pc/fp/sp/lr in the
live register context signed with pointer authentication;
this patch changes RegisterContextUnwind to strip those
bits off of those values as we try to walk the stack.
