2548: Fix probestack r=ptitSeb a=ptitSeb # Description The `skip_stack_gard_page` were failing. The patch first add a trampoline for the PROBEGUARD function on x86_64 build, as this one comes from some runtime and can be too far away from generated code for a regular 32bits relative address (this fix a segfault when a generated function needs a call to probeguard). The patch also add a special case for StackOverflow error, and doesn't check if the error comes from Wasm code (as the stack overflow will comes from a runtime library, generated by the probeguard function).
