Rollup merge of #35444 - alexcrichton:optimize-catch-unwind, r=brson
std: Optimize panic::catch_unwind slightly The previous implementation of this function was overly conservative with liberal usage of `Option` and `.unwrap()` which in theory never triggers. This commit essentially removes the `Option`s in favor of unsafe implementations, improving the code generation of the fast path for LLVM to see through what's happening more clearly. cc #34727
