* Implement wasm trap handlers. This adds signal handlers based on SpiderMonkey's signal-handler code. The functionality for looking up the trap code and wasm bytecode offset isn't yet implemented, but this is a start. I considered rewriting this code in Rust, but decided against it for now as C++ allows us to talk to the relevant OS APIs more directly. Fixes #15. * Compile with -std=c++11. * Refactor InstallState initialization. * Compile with -fPIC. * Factor out the code for calling a wasm function with a given index. * Fix unclear wording in a comment.
