[PTO][IR] CopyOp::getPipe uses srcSpace in isDstGlobal condition

[WenboCodes]

Problem

CopyOp::getPipe() appears to contain a typo in destination-global detection.

Evidence

lib/PTO/IR/PTO.cpp:6310

bool isDstGlobal = (dstSpace == AddressSpace::GM || srcSpace == AddressSpace::MAT);

The second disjunct likely should be dstSpace == AddressSpace::MAT.

Impact

PIPE routing may be incorrect for some copy routes (especially when destination is MAT but source is not MAT).

Expected behavior

Use destination space consistently:

bool isDstGlobal = (dstSpace == AddressSpace::GM || dstSpace == AddressSpace::MAT);

Acceptance criteria

• Fix condition.
• Add route test(s) for combinations involving dst=MAT and dst=GM.
• Verify resulting getPipe() matches intended MTE2/MTE3 behavior.
