Subject: [PATCH] Auto merge of #44066 - cuviper:powerpc64-extern-abi,
r=alexcrichton
powerpc64: improve extern struct ABI
These fixes all have to do with the 64-bit PowerPC ELF ABI for big-endian
targets. The ELF v2 ABI for powerpc64le already worked well.
- Return after marking return aggregates indirect. Fixes #42757.
- Pass one-member float aggregates as direct argument values.
- Aggregate arguments less than 64-bit must be written in the least-
significant bits of the parameter space.
- Larger aggregates are instead padded at the tail.
(i.e. filling MSBs, padding the remaining LSBs.)
New tests were also added for the single-float aggregate, and a 3-byte
aggregate to check that it's filled into LSBs. Overall, at least these
formerly-failing tests now pass on powerpc64:
- run-make/extern-fn-struct-passing-abi
- run-make/extern-fn-with-packed-struct
- run-pass/extern-pass-TwoU16s.rs
- run-pass/extern-pass-TwoU8s.rs
- run-pass/struct-return.rs

Subject: [PATCH] Auto merge of #44440 - cuviper:min_global_align, r=japaric
Add `TargetOptions::min_global_align`, with s390x at 16-bit
The SystemZ `LALR` instruction provides PC-relative addressing for globals,
but only to *even* addresses, so other compilers make sure that such
globals are always 2-byte aligned. In Clang, this is modeled with
`TargetInfo::MinGlobalAlign`, and `TargetOptions::min_global_align` now
serves the same purpose for rustc.
In Clang, the only targets that set this are SystemZ, Lanai, and NVPTX, and
the latter two don't have targets in rust master.
Fixes #44411.
