[NewPM] fixing asserts on deleted loop in -print-after-all IR-printing AfterPass instrumentation might be called on a loop that has just been invalidated. We should skip printing it to avoid spurious asserts. Reviewed By: chandlerc, philip.pfaffe Differential Revision: https://reviews.llvm.org/D54740 llvm-svn: 348887

[NewPM] -print-module-scope -print-after now prints module even after invalidated Loop/SCC -print-after IR printing generally can not print the IR unit (Loop or SCC) which has just been invalidated by the pass. However, when working in -print-module-scope mode even if Loop was invalidated there is still a valid module that we can print. Since we can not access invalidated IR unit from AfterPassInvalidated instrumentation point we can remember the module to be printed *before* pass. This change introduces BeforePass instrumentation that stores all the information required for module printing into the stack and then after pass (in AfterPassInvalidated) just print whatever has been placed on stack.
