89e0f386f3 Be nice to Xcore and the XMOS assembler and avoid quoting section names 
that contain only letters, digits and the characters "_" and ".".

9935bd0819 Add llvm.xcore.waitevent intrinsic. The effect of this intrinsic is to enable 
events on the thread and wait until a resource is ready to event. The vector
of the resource that is ready is returned.

44be1a8d66 Enable machine sinking critical edge splitting. e.g. 
define double @foo(double %x, double %y, i1 %c) nounwind {
  %a = fdiv double %x, 3.2
  %z = select i1 %c, double %a, double %y
  ret double %z
}

Was:
_foo:
        divsd   LCPI0_0(%rip), %xmm0
        testb   $1, %dil
        jne     LBB0_2
        movaps  %xmm1, %xmm0
LBB0_2:
        ret

Now:
_foo:
        testb   $1, %dil
        je      LBB0_2
        divsd   LCPI0_0(%rip), %xmm0
        ret
LBB0_2:
        movaps  %xmm1, %xmm0
        ret

This avoids the divsd when early exit is taken.

3b9d6216a4 fix AsmPrinter::GetBlockAddressSymbol to always return a unique

causes collisions if the name is empty).  This fixes PR6608

ebc64cf780 Lower add (mul a, b), c into MACCU / MACCS nodes which translate
