  Log Message:
  -----------
  [StructurizeCFG] Stop setting DebugLocs in flow blocks (#139088)

Flow blocks are generated code that don't really correspond to any
location in the source, so principally they should have empty DebugLocs.
Practically, setting these debug locs leads to redundant is_stmts being
generated after #108251, causing stepping test failures in the ROCm GDB
test suite.

Fixes SWDEV-502134
