The verifier follows GlobalAlias operands so that it can detect cycles of
alias definitions. It was doing this in a way that caused it to also recurse
through initializers for the GlobalValue aliasees, and it would fail when
an initializer refers to a global that is a declaration and not a definition.
This patch causes it to stop recursing when it hits a global definition.

construction and destruction.
PassRegistrationListener is intended for use as a generic listener.
In some cases, PassRegistrationListener-derived classes were being
created, and automatically registered and de-registered in static
constructors and destructors. Since ManagedStatics are destroyed
prior to program shutdown, this leads to errors where an attempt is
made to access a ManagedStatic that has already been destroyed.

This destructor is run as part of static program termination, and
so all ManagedStatics (including this lock) will have been
destroyed by llvm_shutdown. Furthermore, if there is actually
a race condition during static program termination, then we are
just hiding a bug somewhere else, because other threads should
not be running at this point.

Current MSVC versions don't have move assignment operators, so we
can't rely on them being available in the dll. If we have the
definition, we can just use that directly. This breaks pointer
equality, but should work fine otherwise.
When there is an MSVC version that supports move assignment,
we can key this off the -fmsc-ver option.

We weren't doing this before, so all instruction using the *Helper
classes were considered for any ALU slot.
This fixes a hang in the builtin-char-clz-1.0.generated.cl piglit test.

Previously we would always print the offset as decimal, regardless of
the formatting requested. Now we use the formatImm() helper so the value
is printed as the client (LLDB in the motivating example) requested.
Before:
ldr.w r8, [sp, #180] @ always
After:
ldr.w r8, [sp, #0xb4] @ when printing hex immediates
ldr.w r8, [sp, #0180] @ when printing decimal immediates

Previously there was a separate mode entirely (--hdis vs.
--disassemble). It makes a bit more sense for the immediate printing
style to be a flag for --disassmeble rather than an entirely different
thing.

This is the same problem fixed in r210664 for more types.
The test passes without this fix. For some reason
I'm only hitting this when creating selects lowered
to v2i32 selects.
