ADR 0107: Remove legacy Shared movement Functions

Decision

The independent Shared movement Functions 9, 10, 11, 12, and 14 are removed from the accepted ISA/TLSU operation set. Their encodings are reserved and raise Fault_IllegalInstruction in the 0.58.5 candidate.

Canonical lowering is:

• Shared to GM: TSTORE with optional B.SUBVIEW.
• Local to Shared: ordinary TMOV with optional B.ASSEMBLE.
• Shared to Local: ordinary TMOV with optional B.SUBVIEW.
• Function 13 GMOV remains unchanged.

A source-level frontend may retain sugar only when it lowers mechanically to these canonical forms without quarter selection, defined-mask semantics, or independent readiness/publication behavior.

Consequences

Operation identity, decoder witnesses, catalogs, documentation, and AVS closure must no longer accept the removed variants. The canonical forms share the parent-level readiness and explicit range rules above.
