David Farler 7e8b8f83e8 Emit reflection metadata by default ...

This turns on the remote reflection metadata by default for swift
invocations and the standard library. The size delta for all of the
sections is:

Section __swift3_typeref: 20176
Section __swift3_reflstr: 2556
Section __swift3_fieldmd: 8172
Section __swift3_assocty: 18112

Recognizing that this is a nontrivial increase in binary size, we can
reduce this with a few methods:

- Trie for strings (typerefs and field names are both strings) but would
  need an implementation
- Compress the entire sections: this would need an implementation
  available on all platforms where we support the functionality.
- Don't use the AST mangler but a custom mangling, which may be slightly
  more compact because it can specialize by need and maybe not include
  some mangle nodes that typerefs don't need.
