add integration tests, unwind across FFI boundary ### Integration Tests This commit introduces some new fixtures to the `run-make-fulldeps` test suite. * c-unwind-abi-catch-panic: Exercise unwinding a panic. This catches a panic across an FFI boundary and downcasts it into an integer. * c-unwind-abi-catch-lib-panic: This is similar to the previous `catch-panic` test, however in this case the Rust code that panics resides in a separate crate. ### Add `rust_eh_personality` to `#[no_std]` alloc tests This commit addresses some test failures that now occur in the following two tests: no_std-alloc-error-handler-custom.rs * no_std-alloc-error-handler-default.rs Each test now defines a `rust_eh_personality` extern function, in the same manner as shown in the "Writing an executable without stdlib" section of the `lang_items` documentation here: https://doc.rust-lang.org/unstable-book/language-features/lang-items.html#writing-an-executable-without-stdlib Without this change, these tests would fail to compile due to a linking error explaining that there was an "undefined reference to `rust_eh_personality'." ### Updated hash * update 32-bit hash in `impl1` test ### Panics This commit uses `panic!` macro invocations that return a string, rather than using an integer as a panic payload. Doing so avoids the following warnings that were observed during rollup for the `*-msvc-1` targets: ``` warning: panic message is not a string literal --> panic.rs:10:16 \| 10 \| panic!(x); // That is too big! \| ^ \| = note: `#[warn(non_fmt_panic)]` on by default = note: this is no longer accepted in Rust 2021 help: add a "{}" format string to Display the message \| 10 \| panic!("{}", x); // That is too big! \| ^^^^^ help: or use std::panic::panic_any instead \| 10 \| std::panic::panic_any(x); // That is too big! \| ^^^^^^^^^^^^^^^^^^^^^ warning: 1 warning emitted ``` See: https://github.com/rust-lang-ci/rust/runs/1992118428 As these errors imply, panicking without a format string will be disallowed in Rust 2021, per #78500. 2020-12-11 19:54:47 -06:00			`-include ../tools.mk`
