<pre>
    As requested in review for #144745, this issue tracks further improvements for how exception-handling tables for Windows are handled on AMD64.

Specifically:

* Can NOP padding be avoided in more situations?  There is some discussion of whether UEFI should or should not use NOP padding.
* Can we use INT3 instead of NOP when we know that a CALL is for a no-return function?  This information is a little harder to get at the MachineFunction level, so it may require propagating more information.
* Can we avoid NOP padding when a CALL is before an SEH epilogue but the CALL is within a null region?  Null regions don't require any cleanup, so the NOP can be avoided.
