[Thumb2][MVE] Recognise shuffle truncation patterns suitable for ARMISD::MVETRUNC
I'm helping with the remaining regressions on D127115, and one of my candidate fixes caused some regressions with MVE interleaved shuffles due to poor handling of 'truncation' style shuffle masks (0,2,4,6,...).
This patch attempts to use the ARMISD::MVETRUNC node to handle these cases, based off existing code in LowerTruncate.
It handles both (0,2,4,6,...) and (1,3,5,7,....) 'top' style patterns (assuming no endian problems). I shift down the 'top' patterns - a basic search of ARM docs suggests MVE has some top/bottom truncation/narrowing instructions but I don't seem to be able to get them to be used.

[codegen] Store address of indirect arguments on the stack
With codegen prior to this patch, truly indirect arguments -- i.e.
those that are not `byval` -- can have their debug information lost even
at O0. Because indirect arguments are passed by pointer, and this
pointer is likely placed in a register as per the function call ABI,
debug information is lost as soon as the register gets clobbered.
This patch solves the issue by storing the address of the parameter on
the stack, using a similar strategy employed when C++ references are
passed. In other words, this patch changes codegen from:
```
define @foo(ptr %arg) {
call void @llvm.dbg.declare(%arg, [...], metadata !DIExpression())
```
To:
```
define @foo(ptr %arg) {
%ptr_storage = alloca ptr
store ptr %arg, ptr %ptr_storage
call void @llvm.dbg.declare(%ptr_storage, [...], metadata !DIExpression(DW_OP_deref))
```
Some common cases where this may happen with C or C++ function calls:
1. "Big enough" trivial structures passed by value under the ARM ABI.
2. Structures that are non-trivial for the purposes of call (as per
the Itanium ABI) when passed by value.
A few tests were matching the wrong alloca (matching against the new
alloca, instead of the old one), so they were updated to either match
both allocas or include a `,` right after the alloca type, to prevent
matching against a pointer type.

[OpenMP][JIT] Introduce more debugging configuration options
The JIT is a great debugging tool since we can modify the IR manually
before launching it in an existing test case. The new flasks allow to
skip optimizations, to use the exact given IR, as well as to provide a
finished object file. The latter is useful to try out different backend
options and to have complete freedom with pass pipelines.
Documentation is included. Minimal refactoring was performed to make the
second object fit in nicely.

[OpenMP][JIT] Cleanup JIT interface, caching, and races
The JIT interface was somewhat irregular as it used multiple global
functions. It also did not cache the results of the JIT, hence multiple
GPU systems would perform the work multiple times. Finally, there might
have been races on the state if we have multi-threaded initialization of
different embedded images, or one image initialized on multiple devices.
This patch tries to rectify all of the above. The JITEngine is now a
part of the GenericPluginTy and tied to one target triple. To support
multiple "ComputeUnitKind"s (previously confusingly called Arch or
[M]CPU) and to avoid re-jitting for the same ComputeUnitKind, we keep a
map of JIT results per ComputeUnitKind. All interaction with the JIT
happens through the JITEngine directly, two functions are exposed. Both
use (shared) locks to avoid races and cache the result. All JIT-related
environment variables are now defined together.

[mlir][ods] Rework how transitive use of deprecated defs are handled
The code currently attempting to recursively find uses of a deprecated def has a few deficiences:
* It recurses into all def uses. This is problematic as it also causes any users of a def using a deprecated def, to be considered deprecated, causing a transitive chain of deprecated defs (see `H_ButNotTransitivelyInNonAnonymousDef` in test case for reproducer)
* It did not recurse into other kinds of fields, such as list and DAGs
This patch fixes the issue by reworking the code to properly recurse into inits and not to recurse into def uses unless they are anonymous defs. Since inits (including DAG, List and anonymous defs) are uniqued, the memoization is kept and remains profitable.
