storing an i170 on a 32 bit machine.  This is first
promoted to a trunc-i170 store of an i256.  On a
little-endian machine this expands to a store of
an i128 and a trunc-i42 store of an i128.  The
trunc-i42 store is further expanded to a trunc-i42
store of an i64, then to a store of an i32 and a
trunc-i10 store of an i32.  At this point the operand
type is legal (i32) and expansion stops (legalization
of the trunc-i10 needs to be handled in LegalizeDAG.cpp).
On big-endian machines the high bits are stored first,
and some bit-fiddling is needed in order to generate
aligned stores.

offload to getStore rather than trying to handle
both cases at once (the assertions for example
assume the store really is truncating).

Remove a couple FIXME's for rewriting ObjC interfaces (which are now being rewritten properly).

This commit contains lot's of small tweaks to how we pass around and store SourceLocation's for interfaces/protocols/categories/implementations.

of VariableArrayTypes that appear in TypedefDecls.

for example:

  typedef int T[x][x];

the StmtIterator will iterate over "x" and "x" as subexpressions of
the DeclStmt for T.

where the decl would always be non-NULL.  Moved the check to after the
block to properly tidy up the iterator's state.

of VariableTypeArray types that appear in DeclStmts.

Removed operator-- from StmtIterator.  operator-- added undesired
complexity, and we have no consumers of it.
