This fixes a number of correctness issues from the previous version. Additionally, we use a new
strategy which has much better performance charactersitics and also finds more opportunities to
apply the optimization.

Refine instruction_set inline rules
...
Previously an exact match of the `instruction_set` attribute was required for an MIR inline to be considered. This change checks for an exact match *only* if the callee sets an `instruction_set` in the first place. When the callee does not declare an instruction set then it is considered to be platform agnostic code and it's allowed to be inline'd into the caller.

Fix MIR inlining of asm_unwind
The MIR inlining currently doesn't handle inline asm's unwind edge correctly.
This code will cause ICE:
```rust
struct D;
impl Drop for D {
fn drop(&mut self) {}
}
#[inline(always)]
fn foo() {
let _d = D;
unsafe { std::arch::asm!("", options(may_unwind)) };
}
pub fn main() {
foo();
}
```
This PR fixes this issue. I also take the opportunity to extract common code into a method.

Rollup merge of #93313 - tmiasko:uninhabited, r=tmandry

Check if call return type is visibly uninhabited when building MIR
The main motivation behind the change is to expose information about diverging
calls to the generator transform and match the precision of drop range tracking
which already understands that call expressions with visibly uninhabited types
diverges.
This change should also accept strictly more programs than before. That is
programs that were previously rejected due to errors raised by control-flow
sensitive checks in a code that is no longer considered reachable.
Fixes #93161 .
