James Y Knight f5f1b0e59e [opaque pointer types] Cleanup CGBuilder's Create*GEP.
Some of these functions take some extraneous arguments, e.g. EltSize,
Offset, which are computable from the Type and DataLayout.

Add some asserts to ensure that the computed values are consistent
with the passed-in values, in preparation for eliminating the
extraneous arguments. This also asserts that the Type is an Array for
the calls named "Array" and a Struct for the calls named "Struct".

Then, correct a couple of errors:

1. Using CreateStructGEP on an array type. (this causes the majority
   of the test differences, as struct GEPs are created with i32
   indices, while array GEPs are created with i64 indices)

2. Passing the wrong Offset to CreateStructGEP in TargetInfo.cpp on
   x86-64 NACL (which uses 32-bit pointers).

Richard Smith 5a1104bd3a DR1472: A reference isn't odr-used if it has preceding initialization,
initialized by a reference constant expression.

Our odr-use modeling still needs work here: we don't yet implement the 'set of
potential results of an expression' DR.
