12df91513e Fix handling of double precision loads and stores when Mips1 is targeted. 
Mips1 does not support double precision loads or stores, therefore two single
precision loads or stores must be used in place of these instructions. This 
patch treats double precision loads and stores as if they are legal
instructions until MCInstLowering, instead of generating the single precision
instructions during instruction selection or Prolog/Epilog code insertion.

Without the changes made in this patch, llc produces code that has the same 
problem described in r137484 or bails out when
MipsInstrInfo::storeRegToStackSlot or loadRegFromStackSlot is called before
register allocation.

f969dabf83 After talking with Bill, it seems like the LandingPad handling here is likely 
to be wrong (or at least somewhat suspect).  Leave a FIXME for Bill.

6a475e691d Update SimplifyCFG for atomic operations. 
This commit includes a mention of the landingpad instruction, but it's not
changing the behavior around it.  I think the current behavior is correct,
though.  Bill, can you double-check that?

b9df018555 Avoid evaluating Neon macro arguments more than once by disabling type checks. 
It turns out that the use of "__extension__" in these macros was disabling
the expected "incompatible pointer" warnings, so these type checks were not
doing anything anyway.  They introduced a serious bug by evaluating some
macro arguments twice, which is a big problem for arguments with side effects.
I'll have to find another way to get the right type checking.  Radar 9947657.

b81c3ed76d Fix PR10656. It's only profitable to use 128-bit inserts and extracts 
when AVX mode is one. Otherwise is just more work for the type
