We're seeing a really odd regression with this diff. If you compile the following code with `-target aarch64 -O0 -mgeneral-regs-only`

  #include <stdbool.h>
  bool foo();
  bool ice() {
    return foo();  // <- crashes the compiler during instruction selection
  }

it crashes the compiler. If you instead make it

  #include <stdbool.h>
  bool foo();
  bool ice() {
    bool b = foo();
    return b; 
  }

then it is fine.
