Santiago Aboy Solanes 1d567568f6 [ptr-compr][csa] Loading CompressedXXX (+ Change node) instead of TaggedXXX
We translate loads with TaggedXXX (XXX in {"", "Signed", "Pointer"})
representation in CSA into loads of CompressedXXX +
ChangeCompressedXXXToTaggedXXX in the raw-machine-assembler.

This way, CSA doesn't need to know about Compressed values since we
are introducing an explicit "decompress" node.

Also updating tests that were checking for the load nodes.
