Temporarily revert "SafepointIRVerifier port to new Pass Manager"

to unbreak the modular bots and its follow-up commit.

This reverts commit https://reviews.llvm.org/D59825
because it introduced a

fatal error: cyclic dependency in module 'LLVM_intrinsic_gen': LLVM_intrinsic_gen -> LLVM_IR -> LLVM_intrinsic_gen
