Revert "[SelectionDAG] Add missing setValue calls in visitIntrinsicCall"
This reverts commit 0c64e1b68f36640ffe82fc90e6279c50617ad1cc.
This reverts commit 1142e6c7c795de7f80774325a07ed49bc95a48c9.
It spuriously added !pcsections where they shouldn't be. See added test
case in test/CodeGen/X86/pcsections.ll as an example. The reason is that
the SelectionDAG chains operations in a basic block as "operands"
pointing to preceding instructions. This resulted in setting the
metadata on _all_ instructions preceding the one that should have the
metadata.
Reverting for now because the semantics of !pcsections was completely
buggy now.
When adding pcsections to SDNodes, recursively add them to all values of
the node as well.

Add fix for propagation of !pcsections metadata for expanded atomics,
together with more tests for interesting atomic instructions (based on
