AMDGPU: Match load d16 hi instructions

Also starts selecting global loads for constant address
in some cases. Some end up selecting to mubuf still, which
requires investigation.

We still get sub-optimal regalloc and extra waitcnts inserted
due to not really tracking the liveness of the separate register
halves.

In r288122, we changed vm_page_unwire() so that it returns a Boolean
indicating whether the page's wire count transitioned to zero.  Use that
return value in zbuf_page_free() rather than checking the wire count.

Sync with amd64/arm/arm64/i386/mips pmap change r288256:

Exploit r288122 to address a cosmetic issue.  Since PV chunk pages don't
belong to a vm object, they can't be paged out.  Since they can't be paged
out, they are never enqueued in a paging queue.  Nonetheless, passing
PQ_INACTIVE to vm_page_unwire() creates the appearance that these pages
are being enqueued in the inactive queue.  As of r288122, we can avoid
this false impression by passing PQ_NONE.

Tighten the invariants around LoopBase::invalidate

Summary:
With this change:
 - Methods in LoopBase trip an assert if the receiver has been invalidated
 - LoopBase::clear frees up the memory held the LoopBase instance

This change also shuffles things around as necessary to work with this stricter invariant.

[COFF] Adjust secrel limit check

According to Microsoft's PE/COFF documentation, a SECREL relocation is
"The 32-bit offset of the target from the beginning of its section". By
my reading, the "from the beginning of its section" implies that the
offset is unsigned.

Change from an assertion to an error, since it's possible to trigger
this condition normally for input files with very large sections, and we
should fail gracefully for those instead of asserting.

Compact EhSectionPiece from 32 bytes to 16 bytes.

EhSectionPiece used to have a pointer to a section, but that pointer was
mostly redundant because we almost always know what the section is without
using that pointer. This patch removes the pointer from the struct.

This patch also use uint32_t/int32_t instead of size_t to represent
offsets that are hardly be larger than 4 GiB. At the moment, I think it is
OK even if we cannot handle .eh_frame sections larger than 4 GiB.

[MIRPrinter] Print empty successor lists when they cannot be guessed

This re-applies commit r313685, this time with the proper updates to
the test cases.

Original commit message:
Unreachable blocks in the machine instr representation are these
weird empty blocks with no successors.
The MIR printer used to not print empty lists of successors. However,
the MIR parser now treats non-printed list of successors as "please
guess it for me". As a result, the parser tries to guess the list of
successors and given the block is empty, just assumes it falls through
the next block (if any).

For instance, the following test case used to fail the verifier.
The MIR printer would print

         entry
        /      \
   true (def)   false (no list of successors)
       |
 split.true (use)

The MIR parser would understand this:

[LoopInfo] Make LoopBase and Loop destructors non-public

Summary:
See comment for why I think this is a good idea.

This change also:

 - Removes an SCEV test case.  The SCEV test was not testing anything useful (most of it 
was `#if 0` ed out) and it would need to be updated to deal with a private ~Loop::Loop.
 - Updates the loop pass manager test case to deal with a private ~Loop::Loop.
 - Renames markAsRemoved to markAsErased to contrast with removeLoop, via the usual remove 
vs. erase idiom we already have for instructions and basic blocks.

well.  See the LoopUnroller for a slightly more interesting case.
