[exceptions] Upgrade exception handlers when stack protector is used
Summary:
MSVC provide exception handlers with enhanced information to deal with security buffer feature (/GS).
To be more secure, the security cookies (GS and SEH) are validated when unwinding the stack.
The following code:
```
void f() {}
void foo() {
__try {
f();
} __except(1) {
f();
}
}
```
