Rollup merge of #55834 - ogoffart:union-abi, r=eddyb 
Forward the ABI of the non-zero sized fields of an union if they have the same ABI

This is supposed to fix the performence regression of using MaybeUninit in

Rollup merge of #55827 - ljedrz:various_stashed, r=alexcrichton 
A few tweaks to iterations/collecting

- simplify and speed up `dot::GraphWalk::nodes` for `cfg::CFG`
- `reserve` the capacity for `edges` in `DepGraph::query`
- collect directly to a `HirVec` in `LoweringContext::lower_attrs`
- fix overallocation in `OnDiskCache::serialize`
- preallocate the `new_partitioning` vector in `merge_codegen_units`
- simplify `impl FromHex for str`
- improve the creation of `self_arg_names` in `impl MethodDef`

Rollup merge of #55564 - smaeul:test-fixes-2, r=alexcrichton 
test/linkage-visibility: Ignore on musl targets

DynamicLibrary uses libc's dlsym() function internally to find symbols.
Some implementations of dlsym(), like musl's, only look at dynamically-
exported symbols, as found in shared libraries. To also export symbols
from the main executable, pass --export-dynamic to the linker.

(Plus see [here](https://stackoverflow.com/questions/4184017) and [here](https://stackoverflow.com/questions/6121838) for examples of where this is necessary on glibc as well.)

Rollup merge of #55562 - smaeul:powerpc-linux-musl, r=alexcrichton 
Add powerpc- and powerpc64-unknown-linux-musl targets

Add targets for musl on 32-bit and 64-bit powerpc. This requires some ABI fixes, as musl [uses the ELFv2 ABI on regardless of endianness](http://git.musl-libc.org/cgit/musl/tree/configure?id=8084d6ab57cdb0b8f328d3cdbad3b9d09eaaee04#n638). At the moment, powerpc64 support requires [an LLVM patch](https://reviews.llvm.org/D52013) to select the correct ABI; or I can add [a patch to Rust's LLVM backend](e8eaa2afd5) to always choose the right ABI.

Both architectures are able to run an extended bootstrap, and with some test fixes (e.g. #55561), there are no architecture-dependent test failures on powerpc64 (most failures in `src/test` are existing musl-host-related issues).
