Rollup merge of #105026 - oToToT:aarch64-v8a, r=davidtwco
v8a as default aarch64 target After https://github.com/llvm/llvm-project/commit/8689f5e landed, LLVM takes the intersection of v8a and v8r as default. This commit brings back v8a support by explicitly specifying v8a in the feature list. This should solve #97724. p.s. a bit more context can also be found in https://github.com/llvm/llvm-project/issues/57904#issuecomment-1329555590.
