[mips] Remove two more redundant 'let Predicates = [HasStdEnc]' statements that were missed

Summary:
The InstSE class already initializes Predicates to [HasStdEnc].

No functional change (confirmed by diffing tablegen-erated files before and
after)

[DWARF parser] Compress DIEMinimal even further, simplify building DIE tree.

DIE doesn't need to store a pointer to its parent: we can traverse the DIE tree
only with functions getFirstChild() and getSibling(). Parents must be known
only when we construct the tree. Rewrite setDIERelations() procedure in a more
straightforward way, and get rid of lots of now unused DIEMinimal methods.

No functionality change.
