  [OpenMP] runtime support for efficient partitioning of collapsed triangular loops (#83939)

This PR adds OMP runtime support for more efficient partitioning of
certain types of collapsed loops that can be used by compilers that
support loop collapsing (i.e. MSVC) to achieve more optimal thread load
balancing.

In particular, this PR addresses double nested upper and lower isosceles
triangular loops of the following types

1. lower triangular 'less_than'
   for (int i=0; i<N; i++)
     for (int j=0; j<i; j++)
2. lower triangular 'less_than_equal'
   for (int i=0; i<N; j++)
     for (int j=0; j<=i; j++)
3. upper triangular
   for (int i=0; i<N; i++)
     for (int j=i; j<N; j++)

Includes tests for the three supported loop types.

  [llvm-dwarfdump] Fix parsing DW_CFA_AARCH64_negate_ra_state (#84128)

The saved state of the AARCH64_DWARF_PAUTH_RA_STATE register was not
updated, so `llvm-dwarfdump` continued to dump it as `reg34=1` even if
the correct value is `0`:

```

  [DWARF] Dump an updated location for DW_CFA_advance_loc* (#84274)

When dumping FDEs, `readelf` prints new location values after
`DW_CFA_advance_loc(*)` instructions, which looks quite convenient:

```
> readelf -wf test.o
...
... FDE ... pc=0000000000000030..0000000000000064
  DW_CFA_advance_loc: 4 to 0000000000000034
  ...
  DW_CFA_advance_loc: 4 to 0000000000000038
...
```

This patch makes `llvm-dwarfdump` and `llvm-readobj` do the same.
