Fix and test for assert/crash in v8 inlining of local functions in qml mode

When v8 tries to inline a local function which has been flagged
is_qml_global, the assert "CHECK(location_ != __null)" fails.

This happens because of the early out in RecordTypeFeedback for
is_qml_global.  I've limited the early out to UNALLOCATED
variables with is_qml_global.
