getTypeSourceInfo() without checking for NULL.
FieldDecls may have NULL TypeSourceInfo, and in
fact some FieldDecls generated by Clang -- and
all FieldDecls generated by LLDB -- have no
TypeSourceInfo.

This patch makes IsTailPaddedMemberArray check
for NULL.

off PartialDiagnostic. PartialDiagnostic is rather heavyweight for
something that is in the critical path and is rarely used. So, switch
over to an abstract-class-based callback mechanism that delays most of
the work until a diagnostic is actually produced. Good for ~11k code
size reduction in the compiler and 1% speedup in -fsyntax-only on the
code in <rdar://problem/11004361>.

Add a predefine __WINT_UNSIGNED__, similar to __WCHAR_UNSIGNED__, and test them both for ARM and X86.

Use this to fully fix Sema/format-strings.c for non-x86 platforms.

Fix handling of wint_t - we can't assume wint_t is purely an integer promotion of wchar_t - they may differ in signedness.

Teach ASTContext about WIntType, and have it taken from TargetInfo like WCharType. Should fix test/Sema/format-strings.c for ARM, with the exception of one subtest which will fail if wint_t and wchar_t are the same size and wint_t is signed, wchar_t is unsigned.

There'll be a followup commit to fix that.

It reduces the amount of emitted debug information:
1) DIEs in .debug_info have types DW_TAG_compile_unit, DW_TAG_subprogram,
DW_TAG_inlined_subroutine (for opt builds) and DW_TAG_lexical_block only.
2) .debug_str contains only function names.
3) No debug data for types/namespaces/variables is emitted.
4) The data in .debug_line is enough to produce valid stack traces with
function names and line numbers.

minimal disruption on its clients.

Unlike the previous data-recursive scheme, Traverse*Stmt methods are
always getting called. The base methods of RecursiveASTVisitor will enqueue
the sub-statements instead of calling TraverseStmt on them.

Clients that override a Traverse*Stmt method and call TraverseStmt will
still function as function-recursive traversal; if a client wants to
enqueue a sub-statement in its override method it can do it like this:

[inside the override method]
StmtQueueAction StmtQueue(*this);
StmtQueue.queue(Stmt->getSubStmt());

preserves insertion order for all iteration of specializations.

I've also included a somewhat terrifying testcase that rapidly builds up
a large number of functions. This is enough that any system with ASLR
will have non-deterministic debug information generated for the test
case without the fix here as the debug information is generated in part
by walking these specializations.
