Rollup merge of #132552 - taiki-e:sparc-target-feature, r=workingjubilee 
Add v9, v8plus, and leoncasa target feature to sparc and use v8plus in create_object_file

This adds the following three unstable target features:

- `v9`: SPARC-V9 instructions ([LLVM definition][sparc-v9])
  - Relevant to https://github.com/rust-lang/rust/pull/131222#issuecomment-2453310963
  - Relevant to https://github.com/rust-lang/rust/pull/132472#discussion_r1832606081
  - This is also needed to implement https://github.com/taiki-e/atomic-maybe-uninit/pull/31 (depends on inline assembly support) more robustly.
- `v8plus`: SPARC-V8+ ABI ([LLVM definition][sparc-v8plus])
  - This is added in LLVM 20. In LLVM 19 and older, it is emulated to work the same way as LLVM in each LLVM version.
  - See https://github.com/rust-lang/rust/issues/132585#issuecomment-2453926257 for more.
- `leoncasa`: CASA instruction[^1] of LEON3 and LEON4 processors ([LLVM definition][sparc-leoncasa], LLVM feature name: `hasleoncasa`)
  - This is needed to implement https://github.com/taiki-e/atomic-maybe-uninit/pull/31 (depends on inline assembly support) more robustly.
