[mlir][tblgen] Fix undefined behaviour found by MSVC debug iterators
Incrementing past the end iterator of any container in C++ is immediate undefined behaviour.
This is guaranteed to occur in the loop condition due to the expression cur = earlyIncIt++, which when earlyIncIt is the end iterator (aka we just did the last iteration of the loop), will do an increment on the end iterator.
To fix this, the patch refactors the loop to a more conventional loop using iterators, with the only difference being that the increment happens through the erase operation, which conveniently returns an iterator to the element after the erased element. Thanks to that guarantee there is also no need to use std::list over std::vector.
I also opted to reduce the inner loop find_if, because I felt splitting the "search" and the effects of if it was successful made the code (subjectively) nicer, and also avoided having to add an extra "bool erased" to the outer loop body.

[Codegen][LegalizeIntegerTypes] New legalization strategy for scalar shifts: shift through stack
https://reviews.llvm.org/D140493 is going to teach SROA how to promote allocas
that have variably-indexed loads. That does bring up questions of cost model,
since that requires creating wide shifts.
Indeed, our legalization for them is not optimal.
We either split it into parts, or lower it into a libcall.
But if the shift amount is by a multiple of CHAR_BIT,
we can also legalize it throught stack.
The basic idea is very simple:
1. Get a stack slot 2x the width of the shift type
2. store the value we are shifting into one half of the slot
3. pad the other half of the slot. for logical shifts, with zero, for arithmetic shift with signbit
4. index into the slot (starting from the base half into which we spilled, either upwards or downwards)
5. load
6. split loaded integer
This works for both little-endian and big-endian machines:
https://alive2.llvm.org/ce/z/YNVwd5
And better yet, if the original shift amount was not a multiple of CHAR_BIT,
we can just shift by that remainder afterwards: https://alive2.llvm.org/ce/z/pz5G-K
I think, if we are going perform shift->shift-by-parts expansion more than once,
we should instead go through stack, which is what this patch does.

[ORC] Introduce deferred allocation-actions scheme for MachOPlatform bootstrap.
This patch modifies the MachOPlatform bootstrap process to record allocation
actions for ORC runtime platform support code in a "deferred actions" vector
rather than attaching it to the corresponding LinkGraphs up-front. The deferred
allocation-actions are run after all the platform support code has been loaded
by attaching them to a separate "bootstrap-complete" graph.
This change should allow the mach-o platform support code in the ORC runtime to
use advanced mach-o platform features (e.g. static inits, TLVs), provided that
the support code does not use these features at runtime before the bootstrap
process completes, or after the shutdown process starts. This is a nice
improvement in and of itself but is motivated by specific future plans: we
want to start recording unwind info in the mach-o platform state object*, and
the recording functions will have their own frame info that needs registering.
The deferred allocation-actions scheme allows for this.
* The plan is to add a new unwind-info-lookup path to libunwind to allow it to
call back to the ORC runtime to find unwind sections. This will simplify the
implementation of support for JIT'd compact-unwind info.

[codegen] Add StackFrameLayoutAnalysisPass
Issue #58168 describes the difficulty diagnosing stack size issues
identified by -Wframe-larger-than. For simple code, its easy to
understand the stack layout and where space is being allocated, but in
more complex programs, where code may be heavily inlined, unrolled, and
have duplicated code paths, it is no longer easy to manually inspect the
source program and understand where stack space can be attributed.
This patch implements a machine function pass that emits remarks with a
textual representation of stack slots, and also outputs any available
debug information to map source variables to those slots.
The new behavior can be used by adding `-Rpass-analysis=stack-frame-layout`
to the compiler invocation. Like other remarks the diagnostic
information can be saved to a file in a machine readable format by
adding -fsave-optimzation-record.
