Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.

the result of comparisons are 'int' in C, it doesn't work to
test just the result type of the expression.

This makes the local register allocator about 20% faster.

This is the last of the uses of TryImplicitConversion outside of
overload resolution and InitializationSequence itself.

to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.

Thanks to Dale for expertly hunting it down.

case.  Also, the 0xFF hex literal involved in the shift for ESize64 should be
suffixed "ul" to preserve the shift result.

Implemented printHex*ImmOperand() by copying from ARMAsmPrinter.cpp and added a
test case for DisassembleN1RegModImmFrm()/printHex64ImmOperand().

TryStaticImplicitCast (for references, class types, and everything
else, respectively) into a single invocation of
InitializationSequence.

One of the paths (for class types) was the only client of
Sema::TryInitializationByConstructor, which I have eliminated. This
also simplified the interface for much of the cast-checking logic,
eliminating yet more code.

I've kept the representation of C++ functional casts with <> 1
arguments the same, despite the fact that I hate it. That fix will
come soon. To satisfy my paranoia, I've bootstrapped + tested Clang
with these changes.

struct may cause it to shrink more than one byte.  Before
my recent changes we compiled the new test into:

%0 = type { [6 x i8] }
@x = global %0 { [6 x i8] undef }, align 2        ; <%0*> [#uses=0]

which is obviously bogus.  Now we compile it into:

%0 = type <{ i32, i8, i8 }>
@x = global %0 zeroinitializer, align 2           ; <%0*> [#uses=0]

Where the last byte only is tail padding.

Add a test case for this change which also tests the removal of assert() from
printAddrMode2OffsetOperand().

functional casts over to InitializationSequence, eliminating a caller
of Sema::TryImplicitConversion. We also get access and ambiguity
checking "for free".

More cleanups to come in this routine.
