With opaque pointers, we cannot use the pointer element type to
determine the LocationSize for the AA query. Instead, -aa-eval
tests are now required to have an explicit load or store for any
pointer they want to compute alias results for, and the load/store
types are used to determine the location size.

This may affect ordering of results, and sorting within one result,
as the type is not considered part of the sorted string anymore.

To somewhat minimize the churn, printing still uses faux typed
pointer notation.

This mechanically applies the same changes from D121427 everywhere.

It is excessive to have a diagnostic for STB_LOCAL. Just reuse the invalid

Add more comments /*Lower=*/ and /*Upper=*/ calling generateImmOutOfRangeError.

To optimize the only call site `dyn_cast<ARMExidxSyntheticSection>(first)` and
decrease code size.

If SHT_LLVM_SYMPART is unused, don't iterate over inputSections.

A fake unreachable was created and removed, but never
erased.

We were in between two styles when this file was initially
checked in.

glibc >= 2.33 uses shared functions for stat family functions.
D111984 added support for non-64 bit variants but they
do not appear to be enough as we have been noticing msan
errors on 64-bit stat variants on Chrome OS.

https://discourse.llvm.org/t/parallel-input-file-parsing/60164

initializeSymbols currently sets Defined::section and handles non-prevailing
COMDAT groups. Move the code to the parallel postParse to reduce work from the
single-threading code path and make parallel section initialization infeasible.

Postpone reporting duplicate symbol errors so that the messages have the
section information. (`Defined::section` is assigned in postParse and another
thread may not have the information).

* duplicated-synthetic-sym.s: BinaryFile duplicate definition (very rare) now
  has no section information
* comdat-binding: `%t/w.o %t/g.o` leads to an undesired undefined symbol. This
  is not ideal but we report a diagnostic to inform that this is unsupported.
  (See release note)
* comdat-discarded-lazy.s: %tdef.o is unextracted. The new behavior (discarded
  section error) makes more sense
* i386-comdat.s: switched to a better approach working around
  .gnu.linkonce.t.__x86.get_pc_thunk.bx in glibc<2.32 for x86-32.
  Drop the ancient no-longer-relevant workaround for __i686.get_pc_thunk.bx

Seems to have been added accidentally in 58db03a1 and then
copied into clangd by me (but not actually needed).

This reverts commit c30e6447.
It exposed brittle support for __x86.get_pc_thunk.bx.
Need to think a bit how to support __x86.get_pc_thunk.bx.

Make it behave like the glibc<2.32 .gnu.linkonce usage that we want to work around.

Removing comment out code, looks like debugging code left over from a while ago.

In particular we use these in two places:

1. When building PIC code we no longer need to combine output segments
   into a single segment that can be initialized at `__memory_base`.
   Instead each segment can encode its offset from `__memory_base` in
   its initializer.  e.g.

```
(i32.add (global.get __memory_base) (i32.const offset)
```

2. When building PIC code we no longer need to relocation internalized
   global addresses.  We can just initialize them with their correct
   offsets.

PDLInterp is effectively an internal dialect, so there isn't a need to
stage the switch.

Since Mach-O has a two-level namespace (unlike ELF), we can usually set
this property to true.

(I believe this setting is only available in the new LTO backend, so I
can't really use ld64 / libLTO's behavior as a reference here... I'm
just doing what I think is correct.)

See {D119294} for the work done to calculate the `interposable` used in
this diff.
