This CL adds code to detect situations when we hit
null error through GDT call with non-null receiver.
We achieve this by making receiver's cid part of the
GDT calling convention and checking this cid
in runtime entry responsible for throwing the null
error.
This CL is an attempt to narrow down b/179632636
and collapse various impossible crash reports
into a single native crash cluster by crashing VM
instead of throwing a null error.
