Extend _LeakTrackerRegister from 2 to 4 args (UserPtr, ClassName,
UnitName, Line) so the --debug leak report prints where each leaked
object was allocated. Both QBE and native backends now emit the
extra unit-name string literal and AST line number at every
_ClassAlloc site. Leak report output changes from:
- TBox (rc=1)
to:
- TBox (rc=1) at LeakSite:14
Runtime: bucket size grows from 16 to 32 bytes; LTInsert stores
unit-name ptr + line; _LeakTrackerReport prints the " at unit:line"
suffix.
Native backend: plumb FDebugMode from TCodeGenNative through
TNativeBackend; emit _LeakTrackerEnable in $main; emit
_LeakTrackerRegister at both constructor-call paths.
QBE backend: add FCurrentUnitName, set in Generate/GenerateUnit/
AppendUnit/AppendProgram; extend both _LeakTrackerRegister call
sites with EmitStrLit(FCurrentUnitName) + node.Line.
2766 tests pass (2 new e2e tests), FIXPOINT_OK.
