Restore HashMap performance by allowing some functions to be inlined

Since the hashmap and its hasher are implemented in different crates, we
currently can't benefit from inlining, which means that especially for
small, fixed size keys, there is a huge overhead in hash calculations,
because the compiler can't apply optimizations that only apply for these
keys.

Fixes the brainfuck benchmark in #24014.
