Summary:
This startup code is only intended to be used internally, we shouldn't
export it under a conflicting name. In the future we may package this in
an exportable format.
The Zcb extension has c.lbu, but not c.lb. This patch makes us
prefer LBU over LB if we have a choice which will enable more
compression opportunities.

The lower 2 bits of the opcode must be 0x3. If the lower 2 bits are
0-2, it's a compressed instruction.
Merge 3 slightly different error messages into 1 to reduce code. The
messages differed slightly depending on whether we parsed a string
or an expression. The message gets a little more generic, but is no
more generic than what binutils prints.
Fixes clang crash caused by a stale function pointer.
The bug has been present for a pretty long time, but we were lucky not to

Move responsibility of providing the instance variable name (`this`, `self`) from
`TypeSystem` to `Language`.
`Language` the natural place for this, but also has downstream benefits. Some languages
have multiple `TypeSystem` implementations (ex Swift), and by placing this logic in the
`Language`, redundancy is avoided.
This change relies on the tests from D145348 and D146320.

When we check for similarity, right now there is no order to how it is checked, except for via the suffix tree ordering.
We can reduce how much structural analysis we perform by checking the the regions in decreasing size. In doing so, we know that if two large sections match, each of their contained regions also match. This allows us to skip the structural checking for each smaller section. IT does require that we use the large regions as a "bridge" to create the canonical mapping between the two regions.
This reduces compile time significantly for some benchmarks. It will not perform as well for programs with many small items.

Spinlock symbols are removed from headers in MacOS version 10.12 and greater.
Even though they are deprecated, the symbols remain available on the system.
The TSAN interceptors currently cause a build failure after this version because
of the change in availability of the symbol.
We want to continue intercepting the symbols available on the OS.
So we add forward declarations so that the TSAN interceptors can build.
This is tested with the existing osspinlock_norace test.

In the past, the IR Verifier would bail out at the first broken function
it found. This required trickery with sed to put multiple broken functions
in a single test file.
Now, the Verifier allows for multiple broken functions. The sed trickery
is no longer needed. I've eliminated it.
I've also split the test into two since one of them passes verification
and we need to look at the output IR from 'opt'. The other fails and we
need to look at the diagnostics printed by the Verifier.
This code detected that the type returned from getShiftAmountTy was
too small to hold the constant shift amount. But it used the full
type size instead of scalar type size leading it to crash for
scalable vectors.
This code was necessary when getShiftAmountTy would always
return the target preferred shift amount type for scalars even when
the type was an illegal type larger than the target supported. For
vectors, getShiftAmountTy has always returned the vector type.
Fortunately, getShiftAmountTy was fixed a while ago to detect that
the target's preferred size for scalars is not large enough for the
type. So we can delete this code.
Switched to use getShiftAmountConstant to further simplify the code.
Fixs PR61561.
I came accross this, because a lot of regression tests were saying:
```
(lldb) p argc
error: expression failed to parse:
error: couldn't install checkers, unknown error
```
With this change, error messages provide more detail:
```
(lldb) p argc
error: expression failed to parse:
error: couldn't install checkers:
error: Couldn't lookup symbols:
__objc_load
```
I didn't find a case where `Diagnostics()` is not empty. Also it looks like this isn't covered in any test (yet).

The legacy pass is only used in AMDGPU codegen, which doesn't care about running it in call graph order (it actually has to work around that fact).
Make the legacy pass a module pass and share code with the new pass.

Ex:

(int) $0 = 2
```
Users who wish to enable persistent results can make and use an alias that includes
`--persistent-result on`.
Updates: To recommit this, both TestPersistentResult.py and TestPAlias.py needed to be
updated, as well as the changes in D146230.

This function follows `std::ranges::size` from C++20. It is intended
mainly for generic code that does not know the exact range type.
I did not modify the existing `llvm::size` function because it has a strict
guarantee of O(1) running time, and we cannot guarantee that when we delegate
size check to user-defined size functions.
Use `range_size` to optimize size checks in `zip`* and `enumerate`
functions. Before that, we would have to perform linear scans for ranges
without random access iterators.
This is the last change I have planned in the series that overhauls
`zip`* and `enumerate`.
