[ORC] Add finalization & deallocation actions, SimpleExecutorMemoryManager class

Finalization and deallocation actions are a key part of the upcoming

deallocate concepts (basically "copy-and-mprotect", and "munmap") to include
support for arbitrary registration and deregistration of parts of JIT linked
code. This allows us to register and deregister eh-frames, TLV sections,
language metadata, etc. using regular memory management calls with no additional
IPC/RPC overhead, which should both improve JIT performance and simplify
interactions between ORC and the ORC runtime.

The SimpleExecutorMemoryManager class provides executor-side support for memory
management operations, including finalization and deallocation actions.

This support is being added in advance of the rest of the memory manager
redesign as it will simplify the introduction of an EPC based
RuntimeDyld::MemoryManager (since eh-frame registration/deregistration will be
expressible as actions). The new RuntimeDyld::MemoryManager will in turn allow

[flang] Enforce array conformance in actual arguments to ELEMENTALs

When the shapes of actual arguments to ELEMENTAL procedures are
sufficiently well known during semantics, require them to conform.

3 years ago[Support] Convert BinaryStream class zoo to 64-bit offsets
Nico Weber [Thu, 16 Sep 2021 23:14:52 +0000 (19:14 -0400)]
[Support] Convert BinaryStream class zoo to 64-bit offsets

Most PDB fields on disk are 32-bit but describe the file in terms of MSF
blocks, which are 4 kiB by default.

So PDB files can be a bit larger than 4 GiB, and much larger if you create them
with a block size > 4 kiB.

This is a first (necessary, but by far not not sufficient) step towards
supporting such PDB files.  Now we don't truncate in-memory file offsets (which
are in terms of bytes, not in terms of blocks).

No effective behavior change. lld-link will still error out if it were to
produce PDBs > 4 GiB.

[flang] More precise checks for NULL() operands

Improve checking for NULL() and NULL(MOLD=) when used as
variables and expressions outside the few contexts where
a disassociated pointer can be valid.  There were both
inappropriate errors and missing checks.

[LoopPredication] Report changes correctly when attempting loop exit predication

To make the IR easier to analyze, this pass makes some minor transformations.
After that, even if it doesn't decide to optimize anything, it can't report that
it changed nothing and preserved all the analyses.

[clang][NFC] refactor GlobalMethodPool to encapsulate its map

This refactor changes the GlobalMethodPool to a class that contains
the DenseMap of methods. This is to allow for the addition of a
separate DenseSet in a follow-up diff that will handle method
de-duplication when inserting methods into the global method pool.

Changes:
  - the `GlobalMethods` pair becomes `GlobalMethodPool::Lists`
  - the `GlobalMethodPool` becomes a class containing the `DenseMap` of methods
  - pass through methods are added to maintain most of the existing code without changing `MethodPool` -> `MethodPool.Methods` everywhere
