* Generate trampolines based on signatures Instead of generating a trampoline-per-function generate a trampoline-per-signature. This should hopefully greatly increase the cache hit rate on trampolines within a module and avoid generating a function-per-function. * Update crates/runtime/src/traphandlers.rs Co-Authored-By: Sergei Pepyakin <s.pepyakin@gmail.com> Co-authored-by: Sergei Pepyakin <s.pepyakin@gmail.com>
