Rollup merge of #127483 - BertalanD:no_sanitize-global-var, r=rcvalle
Allow disabling ASan instrumentation for globals AddressSanitizer adds instrumentation to global variables unless the [`no_sanitize_address`](https://llvm.org/docs/LangRef.html#global-attributes) attribute is set on them. This commit extends the existing `#[no_sanitize(address)]` attribute to set this; previously it only had the desired effect on functions. (cc https://github.com/rust-lang/rust/issues/39699)
