Modify the Unix signal handler to redirect execution to a Go sigpanic function instead of printing an error and re-raising the signal. The C signal handler modifies the ucontext to make the faulting instruction appear to have called tinygo_sigpanic, which then calls runtimePanic with the appropriate message. Supported on all architectures TinyGo targets on Linux and Darwin: x86_64, i386, aarch64, ARM, and MIPS. Also registers SIGFPE, which was previously not handled at all.
