[Sparc] Correctly handle call to functions with ReturnsTwice attribute.

In sparc, setjmp stores only the registers %fp, %sp, %i7 and %o7. longjmp restores
the stack, and the callee-saved registers (all local/in registers: %i0-%i7, %l0-%l7)
using the stored %fp and register windows. However, this does not guarantee that the longjmp
will restore the registers, as they were when the setjmp was called. This is because these
registers may be clobbered after returning from setjmp, but before calling longjmp.

This patch prevents the registers %i0-%i5, %l0-l7 to live across the setjmp call using the register mask.

[SystemZ] Add NC, OC and XC

For now these are just used to handle scalar ANDs, ORs and XORs in which
all operands are memory.

ARM: Add GPR register class excluding LR for use with the ADR instruction.

This improves code generation for jump tables by avoiding the emission of "mov pc, lr" which could fool the processor into believing this is a return from a function causing mispredicts. The code generation logic for jump tables uses ADR to materialize the address of the jump target.

Patch by Daniel Stewart!

Reverting 190043 for now.

Solution is not sufficient to prevent 'mov pc, lr' being emitted for jump table code.
Test case doesn't trigger the added functionality.

Add AArch32 DCPS{1,2,3} and HLT instructions.


These were pretty straightforward instructions, with some assembly support
required for HLT.

The ARM assembler is keen to split the instruction mnemonic into a
(non-existent) 'H' instruction with the LT condition code. An exception for
HLT is needed.

HLT follows the same rules as BKPT when in IT blocks, so the special BKPT
hadling code has been adapted to handle HLT also.

Regression tests added including diagnostic tests for out of range immediates
and illegal condition codes, as well as negative tests for pre-ARMv8.

This removes the custom ISD Node: MEMBARRIER and replaces it

R600: Fix segfault in R600TextureIntrinsicReplacer

This pass was segfaulting when it ran into a non-intrinsic function
call.  Function calls are not supported, so now instead of segfaulting,
we will get an assertion failure with a nice error message.

I'm not sure how to test this using lit.
