The result is recursively simplified and constant conditionals are pruned, so that dead blocks are removed even for -O0. This allows inline asm blocks with operand constraints to work all the time. The new pass replaces the existing lowering in the codegen-prepare pass and fallbacks in SDAG/GlobalISEL and FastISel. The latter now assert on the intrinsics.

This happens when we sink the instruction into a loop, but cannot remove the originals. The Use is updated, which might in fact be a Use from the second instruction to the first. This attempts to fix that by reversing the order of instruction that are sunk, and ensuring that we update the uses on new instructions if they have already been sunk, not the old ones.

This is useful for various MVE instructions, such as vmla and others that take R registers. Loop tests have been added to the vmla test file to make sure vmlas are generated in loops.
