DebugInfo: Rename CreatePointerType to getOrCreateTypeDeclaration

To make this more consistent with 'getOrCreateType' & clarify the
distinction between the two. The only thing I couldn't quite communicate
in the name is that getOrCreateTypeDeclaration may actually produce a
full definition (in -fno-limit-debug-info) but the point is to call it
whenever only a declaration is needed & the implementation can choose
whether to provide a declaration or definition.

(also, unfortunately, getOrCreateType can produce declarations too - we
should sure this up by making it not do that - any caller that can
tolerate a declaration should be calling getOrCreateTypeDeclaration
instead)

replacements for others, we now notify the WhitespaceManager of the

Try a bit harder to disambiguate. This is mostly straightforward, but for
=-style initializers, we actually need to know where an expression ends:

  [foo = bar baz]

  [foo = bar + baz]

is a lambda-introducer. Handle this by parsing the expression eagerly, and
replacing it with an annotation token. By chance, we use the *exact same*
parsing rules in both cases (except that we need to assume we're inside a
message send for the parse, to turn off various forms of inapplicable
error recovery).
