in `tests/ui/asm/aarch64/parse-error.rs`, only test cases specific to that target
this is more in line with the x86 parse error tests at https://github.com/rust-lang/rust/blob/master/tests/ui/asm/x86_64/x86_64_parse_error.rs. We could at this point use minicore so that these tests run no matter the host target?
`tests/ui/asm/aarch64/parse-error.rs` was mostly a copy of https://github.com/rust-lang/rust/blob/master/tests/ui/asm/parse-error.rs, though a bit out of date. The only aarch64-specific tests are those that talk about register names. Here is a diff between those two files:
