- NonLoc::MakeVal() would use sizeof(unsigned) (literally) instead of consulting
  ASTContext for the size (in bits) of 'int'. While it worked, it was a
  conflation of concepts and using ASTContext.IntTy is 100% correct.
- RegionStore::getSizeInElements() no longer assumes that a VarRegion has the
  type "ConstantArray", and handles the case when uses use ordinary variables
  as if they were arrays.
- Fixed ElementRegion::getRValueType() to just return the rvalue type of its
  "array region" in the case the array didn't have ArrayType.
- All of this fixes <rdar://problem/6541136>

This results in a 1.7% improvement for "Cocoa.h". If we can figure out how to return a "Decl *", rather than a Sema::LookupResult(), we will likely bump the speedup from 1.7%->2.5%. I verified this, however couldn't get it to work without breaking a fair number of C++ test cases. Will discuss with Doug offline.

represents an implicit value-initialization of a subobject of a
particular type. This replaces the (ab)use of CXXZeroValueInitExpr
within initializer lists for the "holes" that occur due to the use of
C99 designated initializers.

The new test case is currently XFAIL'd, because CodeGen's
ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be
taught to value-initialize when it sees ImplicitValueInitExprs.

Eliminate infinite looping in a wacky case with designated initializers. Simplifies (somewhat) the actually checking of the initializer expression following the designators

llvm-svn: 63257

The previous interface was very confusing. This is much more explicit, which will be easier to understand/optimize/convert.

The plan is to eventually deprecate both of these functions. For now, I'm focused on performance.

  - 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

    more than once. We warn about this.

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.
