llvm-mc: Add option for prefering hex format disassembly.

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.

ARM: honor hex immediate formatting for ldr/str i12 offsets.

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

R600: Set correct InstrItinClass for instructions using *Helper classes

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.

Don't acquire the mutex during the destructor of PassRegistry.

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.

Teach LoopUnrollPass to respect loop unrolling hints in metadata.

The Clang change that produces this metadata was committed in r210667

Do not register and de-register PassRegistrationListeners during
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.

Fix verifier for GlobalAliases to avoid recursing into global initializers.

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.
