The ARM stuff already calls the Resume function, not the Resume_or_Rethrow. It
turns out that it could cause an infinite loop in some situations. If this code
is triggered and it converts a cleanup into a catchall, but that cleanup was in
already in a cleanup, then the _Unwind_SjLj_Resume could infinite loop. I.e.,
the code doesn't consume the exception object and passes it on to
_Unwind_SjLj_Resume. But _USjLjR expects it to be consumed (since it's landing
at a catchall instead of a cleanup). So it uses the values that are presently
there, which are the values that tell it to jump to the fake landing pad.

Simplify the eviction policy by making the failsafe explicit.
When assigned ranges are evicted, they are put in the RS_Evicted stage and are
not allowed to evict anything else. That prevents looping automatically.
When evicting ranges just to get a cheaper register, use only spill weights to
find the possible candidates. Avoid breaking hints for this purpose, it is not
worth it.
Start implementing more complex eviction heuristics, guarded by the temporary
-complex-eviction flag. The initial version permits a heavier range to be
evicted if it doesn't have any uses where the evicting range is live. This makes
it a good candidate for live ranfge splitting.

This only affects targets like Mips where branch instructions may kill virtual

inserts new ones while LiveVariables keeps a list of pointers to instructions

When generating against the Win64 EH scheme, set the handler to the GCC-specific

At this moment, only GCC-style exceptions are supported. Other kinds

GCC-style exceptions!

Implement and document the llvm.eh.resume intrinsic, which is

DWARF EH preparation into a call to _Unwind_Resume (or _Unwind_SjLj_Resume

exception value and the selector value as arguments, meaning that there
is zero effort in recovering these; however, the frontend is required
to pass these down, which is not actually particularly difficult.
Also document the behavior of landing pads a bit better, and make it
clearer that it's okay that personality functions don't always land at
landing pads. This is just a fact of life. Don't write optimizations that
