[LowerTypeTests] Add ENDBR to .cfi.jumptable for x86 Indirect Branch Tracking
Similar to D81251 for AArch64 BTI. This fixes `./a.out test` for
```
void foo(void) {}
void bar(void) {}
static void (*fptr)(void);
int main(int argc, char **argv) {
if (argv[1]) fptr = foo;
else fptr = bar;
fptr();
}
```
