Use ConcurrentQueue<T> in ThreadPool

Use the same ConcurrentQueue<T> now being used in corefx in ThreadPool instead of ThreadPool's custom queue implementation (which was close in design to the old ConcurrentQueue<T> implementation).

Commit migrated from https://github.com/dotnet/coreclr/commit/cba50e660a5e8073a820e7c55fce705cb5b973f6

Port ConcurrentQueue<T> back from corefx

It's not exposed from CoreLib, but a) as long as the code is here it's good to have it in sync, and b) we can use it in ThreadPool rather than having a separate concurrent queue implementation (which is very similar to the old ConcurrentQueue design).

I see changes where storeIndir is used now instead of
a BLK copy, which is an IR shape improvement.

This improves codegen for SIMD8, degrades it for SIMD12 (due
to encoding size differences with SSE instructions, though
the IR looks better), and is neutral for SIMD16, in the
VectorReturn test.

Fix morphing of block op assignments

During morphing, block op assignments had their children set to
the "IND" morph context. This is incorrect. Previously, block
ops would "incorporate" the "IND-ness" of their children. However,
now, the operands will be a IND/BLK/OBJ node explicitly. Deleting
this incorrect code enables other changes, not yet merged, to work.

This causes no amd64 SPMI desktop asm diffs.

Stop address mode building in TreeNodeInfoInit pass

During Lower, TryCreateAddrMode() will try to find address
modes and convert them to GT_LEA by calling genCreateAddrMode().
Later, the TreeNodeInfoInit() pass walks the IR annotating
nodes with register requirements. It was also calling
genCreateAddrMode() and then clearing various previously
created register requirements, but not actually changing the
node to a GT_LEA. In some cases (in new code I have not checked
in yet), this was leading to code that codegen couldn't handle.
It turns out this second call to genCreateAddrMode() is
unnecessary (and undesireable), so I've removed it. This causes
no asm diffs on amd64 or x86 (run on desktop: superpmi
and ngen, respectively).

Don't require write barrier for assignment to ByRef

The legacy code gen was hitting an assert when trying to use a write barrier for ByRef to ByRef assignment. RyuJIT is also generating an unnecessary write barrier but the assert is not there. As ByRefs are never in GC locations, don't require a write barrier.
