use minicore for more tests

[RalfJung]

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?
