Problem: PCM file includes references to all module maps used in compilation which created PCM. This problem leads to PCM-rebuilds in distributed compilations as some module maps could be missing in isolated compilation. (For example in our distributed build system we create a temp folder for every compilation with only modules and headers that are needed for that particular command). Solution: Add only affecting module map files to a PCM-file. Reviewed By: rsmith Differential Revision: https://reviews.llvm.org/D106876
