[ThinLTO] Don't rely on debug output for thinlto_samplepgo_icp3 test

aganea · aganea · commit 934d4feab1f5 · 2020-03-25T14:38:20.000-04:00
Because using -print-imports is not thread-safe, make the test rely on llvm-dis instead. Also cover the ICALL-PROM part as intended originally. Differential Revision: https://reviews.llvm.org/D76775
