I’m seeing failures after this commit:
```c++
void a();
struct b {};
typedef enum {} c;
c d;
struct e {
e(b = b());
};
void f() {
switch (d) {
g:
new e;
default:
a();
}
}
```
```console
$ clang -target x86_64-linux-gnu -O2 -c repro.cpp
Instruction does not dominate all uses!
%call = call noalias noundef nonnull ptr @_Znwm(i64 noundef 1) #5
call void @_ZdlPvm(ptr noundef %call, i64 noundef 1) #7
fatal error: error in backend: Broken module found, compilation aborted!
```
Will push a revert soon.
