[MSSA][NewPM] Handle tests with -print-memoryssa

-print-memoryssa in legacy PM is print<memoryssa> in NPM.
Pin tests with -print-memoryssa to legacy PM.
Add corresponding tests for NPM where missing.
This fixes "unknown pass name 'print-memoryssa'".

Some tests still fail in Analysis/MemorySSA due to other passes that
haven't been ported.

pr43427.ll and pr43438.ll required adding -aa-pipeline=basic-aa,
-loop-simplify (since it doesn't run on legacy PM by default), and
decrementing some of the MemoryPhi numbers.

[CMake] Simplify CMake handling for zlib

Rather than handling zlib handling manually, use find_package from CMake
to find zlib properly. Use this to normalize the LLVM_ENABLE_ZLIB,
HAVE_ZLIB, HAVE_ZLIB_H. Furthermore, require zlib if LLVM_ENABLE_ZLIB is
set to YES, which requires the distributor to explicitly select whether
zlib is enabled or not. This simplifies the CMake handling and usage in
the rest of the tooling.

This is a reland of abb0075 with all followup changes and fixes that
should address issues that were reported in PR44780.

[ELF] Allow SHF_LINK_ORDER sections to have sh_link=0

Part of

The semantics of SHF_LINK_ORDER have been extended to represent metadata
sections associated with some other sections (usually text).

The associated text section may be discarded (e.g. LTO) and we want the
metadata section to have sh_link=0 (D72899, D76802).

Normally the metadata section is only referenced by the associated text
section. sh_link=0 means the associated text section is discarded, and
the metadata section will be garbage collected. If there is another
section (.gc_root) referencing the metadata section, the metadata
section will be retained. It's the .gc_root consumer's job to validate
the metadata sections.

  # This creates a SHF_LINK_ORDER .meta with sh_link=0
  .section .meta,"awo",@progbits,0
  .section .meta,"awo",@progbits,foo

  .section .gc_root,"a",@progbits
  .quad 1b
  .quad 2b

[mlir] [VectorOps] Add masked load/store operations to Vector dialect

The intrinsics were already supported and vector.transfer_read/write lowered
direclty into these operations. By providing them as individual ops, however,
clients can used them directly, and it opens up progressively lowering transfer
operations at higher levels (rather than direct lowering to LLVM IR as done now).

[JumpThreading] Allow duplicating a basic block into preds when its branch condition is freeze(phi)

This is the last JumpThreading patch for getting the performance numbers shown at .

This patch makes ProcessBlock call ProcessBranchOnPHI when the branch condition
is freeze(phi) as well (originally it calls the function when the condition is
phi only).

Since what ProcessBranchOnPHI does is to duplicate the basic block into
predecessors if profitable, it is still valid when the condition is freeze(phi)

    p = phi [a, pred1] [b, pred2] = freeze p
    br, ...
  pred1: = freeze a
    br, ...
    p.fr2 = freeze b
    br p.fr2, ...

The fix is the make the destructor virtual. Neither it nor the
constructor need to be public, so make them protected.
