[MachineLICM][WinEH] Don't hoist register reloads out of funclets

This fixes https://github.com/llvm/llvm-project/issues/60766

With MSVC style exception-handling (funclets), no registers are
alive when entering the funclet so they must be reloaded from the
stack.  MachineLICM can sometimes hoist such reloads out of the
funclet which is not correct, the register will have been clobbered
when entering the funclet.  This can happen in any loop that
contains a try-catch.

This has been tested on x86_64-pc-window-msvc.  I'm not sure if
funclets work the same on the other windows archs.
