initializers.

  - We now initialize unions properly when a member other than the
    first is named by a designated initializer.
  - We now provide proper semantic analysis and code generation for
    GNU array-range designators *except* that side effects will occur
    more than once. We warn about this.

 - Merged into single ComplexEvaluator, these share too much logic to
   be worth splitting for float/int (IMHO). Will split on request.

The approach I've taken in this patch is relatively straightforward,
although the code itself is non-trivial. Essentially, as we process
an initializer list we build up a fully-explicit representation of the
initializer list, where each of the subobject initializations occurs
in order. Designators serve to "fill in" subobject initializations in
a non-linear way. The fully-explicit representation makes initializer
lists (both with and without designators) easy to grok for codegen and
later semantic analyses. We keep the syntactic form of the initializer
list linked into the AST for those clients interested in exactly what
the user wrote.

Known limitations:
  - Designating a member of a union that isn't the first member may
    result in bogus initialization (we warn about this)
  - GNU array-range designators are not supported (we warn about this)

retain/release checker: Always generate an "autorelease" summary for an "autorelease" message, and have the summary processing logic treat it as a no-op in GC mode.  This change is motivated to encode more of the semantics in the summaries themselves for eventual better diagnostics.

This removes ~10% of the calls to Sema::isTypeName(), which amount to a little less than a 1% reduction in usertime (for Cocoa.h).

new isOperationLegalOrCustom, which does what isOperationLegal
previously did.

Update a bunch of callers to use isOperationLegalOrCustom
instead of isOperationLegal. In some case it wasn't obvious
which behavior is desired; when in doubt I changed then to
isOperationLegalOrCustom as that preserves their previous
behavior.

This is for the second half of PR3376.
