improve error message when `global_asm!` uses `asm!` options

specifically, what was

    error: expected one of `)`, `att_syntax`, or `raw`, found `preserves_flags`
      --> $DIR/bad-options.rs:45:25
       |
    LL | global_asm!("", options(preserves_flags));
       |                         ^^^^^^^^^^^^^^^ expected one of `)`, `att_syntax`, or `raw`

is now

    error: the `preserves_flags` option cannot be used with `global_asm!`
      --> $DIR/bad-options.rs:45:25
       |
    LL | global_asm!("", options(preserves_flags));
       |                         ^^^^^^^^^^^^^^^ the `preserves_flags` option is not meaningful for global-scoped inline assembly

mirroring the phrasing of the [reference](https://doc.rust-lang.org/reference/inline-assembly.html#options).

This is also a bit of a refactor for a future `naked_asm!` macro (for use in `#[naked]` functions). Currently this sort of error can come up when switching from inline to global asm, or when a user just isn't that experienced with assembly. With  `naked_asm!` added to the mix hitting this error is more likely.
