.debug_gnu_pub{names,types}: Stabilize iteration order
StringMap iteration order is not guaranteed to be deterministic

.debug_gnu_pub{names,types}: Stabilize iteration order
StringMap iteration order is not guaranteed to be deterministic
(https://llvm.org/docs/ProgrammersManual.html#llvm-adt-stringmap-h).
Sort by DIE offset (which looks like a pre-order traversal order).

Recommit "[Support] change StringMap hash function from djbHash to xxHash"
This reverts commit 37eb9d13f891f7656f811516e765b929b169afe0.
Test failures have been fixed:
- ubsan failure fixed by 72eac42f21c0f45a27f3eaaff9364cbb5189b9e4
- warn-unsafe-buffer-usage-fixits-local-var-span.cpp fixed by
03cc52dfd1dbb4a59b479da55e87838fb93d2067 (wasn't related)
- test-output-format.ll failure was spurious, build failed at
https://lab.llvm.org/buildbot/#/builders/54/builds/3545 (b4431b2d945b6fc19b1a55ac6ce969a8e06e1e93)
but passed at
https://lab.llvm.org/buildbot/#/builders/54/builds/3546 (5ae99be0377248c74346096dc475af254a3fc799)
which is before my revert
https://github.com/llvm/llvm-project/compare/b4431b2d945b6fc19b1a55ac6ce969a8e06e1e93...5ae99be0377248c74346096dc475af254a3fc799
Original commit message:
Depends on https://reviews.llvm.org/D142861.
Alternative to https://reviews.llvm.org/D137601.
xxHash is much faster than djbHash. This makes a simple Rust test case with a large constant string 10% faster to compile.
Previous attempts at changing this hash function (e.g. https://reviews.llvm.org/D97396) had to be reverted due to breaking tests that depended on iteration order.
No additional tests fail with this patch compared to `main` when running `check-all` with `-DLLVM_ENABLE_PROJECTS="all"` (on a Linux host), so I hope I found everything that needs to be changed.

See original comment in 560ce2c70fb1fe8e4b9b5e39c54e494a50373ba8
Baiscally the default seed value results in less collision, but changes the
iteration order, which matters for a few test cases.
