Rollup merge of #134760 - jieyouxu:enable-branch-protection-check-IBT, r=lqd
Migrate `branch-protection-check-IBT` to rmake.rs - The Makefile version *never* ran because of Makefile syntax confusion because `ifeq ($(filter x86,$(LLVM_COMPONENTS)),x86_64)` [compares `x86` to `x86_64`, which always evaluates to false](https://github.com/rust-lang/rust/pull/126720#discussion_r1646808973). - The test would've always failed because precompiled std is not built with `-Z cf-protection=branch`, but linkers require all input object files to indicate IBT support in order to enable IBT for the executable, which is not the case for std. - Thus, the test input file is instead changed to a `no_std` program. - The test is currently limited to only `x86_64-unknown-linux-gnu` host, there are various other problems when the test is cross-compiled that I didn't want to fix atm, and is left as an exercise for the `-Z cf-protection` implementers. The GNU property note was added by #110304 in order to address #103001. Partially supersedes #129156. The rmake.rs port was initially authored by `@Rejyr` in #126720. This PR is co-authored with `@Oneirical` and `@Rejyr.` r? `@bjorn3` or reroll try-job: x86_64-mingw-1 try-job: x86_64-mingw-2 try-job: x86_64-msvc try-job: x86_64-apple-1 try-job: x86_64-apple-2
