Introduce a GCStatepointInst type analogous to IntrinsicInst subclasses

Back when we had CallSite, we implemented the current Statepoint/ImmutableStatepoint structure in analogous manner.  Now that CallSite has been removed, the structure used for statepoints looks decidely out of place.  gc.statepoint is one of the small handful of intrinsics which are invokable.  Because of this, it can't subclass IntrinsicInst as is idiomatic.

This change simply introduces the GCStatepointInst class, restructures the existing Statepoint/ImmutableStatepoint types to wrap it.  I will be landing a series of changes to sink functionality into GCStatepointInst and updating callers to be more idiomatic.

Do not warn that an expression of the form (void)arr; is unused when
arr is a volatile non-local array.

This fixes a recent regression exposed by removing lvalue-to-rvalue
conversion of discarded volatile arrays. In passing, regularize the
rules we use to determine whether '(void)expr;' warns when expr is a
volatile glvalue.

Sink first bit of functionality from Statepoint to GCStatepointInst

Starting with the obvious stuff.  I initially tried to include the inline operand sequences too, but managed to get code which confused *me*.  Since several parts of those are being entirely removed in the near future, I may defer that portion until the cleanup is done.

[Statepoint] Replace uses of isX functions with idiomatic isa<X>

Now that all of the statepoint related routines have classes with isa support, let's cleanup.

I'm leaving the (dead) utitilities in tree for a few days so that I can do the same cleanup downstream without breakage.

[Statepoint] Reduce scope of usage of ImmutableStatepoint

Can't quite fully remove it yet as some more items need sunk the GCStatepointInst class from the wrapper, but we can at least reduce scope.

[Driver][X86] Support branch align options with LTO

Summary: Before this patch, we use two different ways to pass options to align branch
depending on whether LTO is enabled. For example, `-mbranches-within-32B-boundaries`
w/o LTO and `-Wl,-plugin-opt=-x86-branches-within-32B-boundaries` w/ LTO.  It's
inconvenient, so this patch unifies the way: we only need to pass options like
`-mbranches-within-32B-boundaries` to align branches, no matter LTO is enabled or not.
