fc8713ff74 Don't replace *all* uses with the new stuff. 
This is not necessarily the first or dominating use of the EH values. The IR
breaks if it's not. So replace the specific value in the instruction with the
new value.

cfcccef926 Look at the end of the entry block for an invoke. 
The invoke could be at the end of the entry block. If it's the only one, then we
won't process all of the landingpad instructions correctly. This code is
currently ugly, but should be made much nicer once the new EH switch is thrown.

5aa29a0cff Move ARM frame-unwinding EHABI handling a touch earlier. 
It should go before AsmPrinter MC pseudo expansion since it's based on
MachineInstr, not MCInst. Otherwise any frame related pseudo instructions
may be missed.

cefe4c9c48 Clean up Thumb load/store multiple definitions. 
There is no non-writeback store multiple instruction in Thumb1, so
don't define one. As a result load multiple is the only instantiation of
the multiclass, so refactor that away entirely.

3bde6fe0df Introduce a pass to insert vzeroupper instructions to avoid AVX to 
SSE transition penalty. The pass is enabled through the "x86-use-vzeroupper"
llc command line option. This is only the first step (very naive and
conservative one) to sketch out the idea, but proper DFA is coming next
to allow smarter decisions. Comments and ideas now and in further commits
will be very appreciated.

aef508dfc1 Split the landing pad's edge. Then for all uses of a landingpad instruction's 
value, we insert a load of the exception object and selector object from memory,
which is where it actually resides. If it's used by a PHI node, we follow that
to where it is being used. Eventually, all landingpad instructions should have
no uses. Any PHI nodes that were associated with those landingpads should be
removed.
