[DebugInfo][GlobalOpt] Fix -debugify for globalopt shrinking globals to booleans.
Summary:
TryToShrinkGlobalToBoolean, when possible, will split store <value> + load <value> into store <bool> + select <bool ? value : 0>. This preserves DebugLoc during that pass.
Fixes PR37959. The test case here is the simplified .ll for:
```
static int foo;
int bar() {
foo = 5;
return foo;
}
```
