Auto merge of #147812 - RalfJung:more-minicore, r=jieyouxu

use minicore for more tests

r? `@jieyouxu`

Unfortunately this doesn't work for all tests; minicore sometimes fails to build with errors like
```
rustc-LLVM ERROR: ILP32E cannot be used with the D ISA extension
```
and
```
error: the target features paca, pacg must all be either enabled or disabled together
```
These errors are meant to be triggered in the tests, but not in minicore.

It seems like all ``@compile-flags`` are forwarded to minicore. Maybe we should exclude `-Ctarget-feature` from that? Or provide some way to set flags only for the current file, not minicore?
