rustc: Tweak visibility of some lang items This commit tweaks the linker-level visibility of some lang items that rustc uses and defines. Notably this means that `#[panic_implementation]` and `#[alloc_error_handler]` functions are never marked as `internal`. It's up to the linker to eliminate these, not rustc. Additionally `#[global_allocator]` generated symbols are no longer forced to `Default` visibility (fully exported), but rather they're relaxed to `Hidden` visibility). This symbols are not needed across DLL boundaries, only as a local implementation detail of the compiler-injected allocator symbols, so `Hidden` should suffice.

use ignore directives for run-make tests This makes the tests easier to read, and makes it possible to tell which tests aren't being run on the host platform. Fixes #56704. 2019-01-06 16:27:57 -05:00
