No testcase yet - it seems we're exposing generic codegen bugs.

just issues an error for the moment. The front end won't yet generate these
intrinsics for ARM, so this is behind the scenes until complete.

Based on the patch by Brian Lucas!

memory barrier instructions by definition have side effects. This prevents the post-RA scheduler from moving them around.

This is used in some weird cases like general dynamic TLS model.

Add memory barrier intrinsic support for ARM. Moving towards adding the atomic operations intrinsics.

vector_shuffle (scalar_to_vector (i32 load (ptr + 4))), undef, <0, 0, 0, 0>
=>
vector_shuffle (v4i32 load ptr), undef, <1, 1, 1, 1>

iff ptr is 16-byte aligned (or can be made into 16-byte aligned).

Move isConsecutiveLoad to SelectionDAG. It's not target dependent and it's primary used by selectdag passes.

- Also support the 'q' NEON registers asm code.

Reduce (cmp 0, and_su (foo, bar)) into (bit foo, bar). This saves extra instruction. Patch inspired by Brian Lucas!

current form, it is too expensive in compile time.
