Michael Kruse d6c2ca8dd2 [DeLICM] Avoid assertion on out-of-quota.
An assertion was not prepared to be passed a nullptr because the
out-of-quota limit was exceeded.  Bail-out before the assertion
since the assertion does not apply on out-of-quote.

This fixes llvm.org/PR37477.

; This causes an assertion to fail on out-of-quota after 1000000 operations.
; (The error was specific to -polly-delicm-max-ops=1000000 and changes
; in the implementation are likely to change the number of operations
; up to the point where the error uses to occur)
