as far as I know, target features 1.1 is not stable #69098 -- is this instability enforced at the declaration site? I guess probably so.

…komatsakis Add DerefOfRawPointer and CallToFunctionWith to THIR unsafeck Extends THIR unsafeck to check for two more cases of unsafe operations: dereferences of raw pointers and calls to functions with `#[target_feature]` (RFC 2396). The check for the latter is pretty much copy-pasted from the existing MIR equivalent. This will clash with rust-lang#83842 and rust-lang#85273 which are arguably more important, let's maybe focus on getting those merged first, this can wait. r? `@nikomatsakis` cc rust-lang/project-thir-unsafeck#7
