    Handles source subtractions like SOURCES -= painting/qdrawhelper.cpp
    by creating a new scope with a new condition containing all addition
    and subtraction conditions.

    Algorithm is as follows:
    - Go through each scope and find files in SOURCES starting with "-"
    - Save that file and the scope condition in modified_sources dict.
    - Remove the file from the found scope (optionally remove the
      NO_PCH_SOURCES entry for that file as well).
    - Go through each file in modified_sources dict.
    - Find scopes where the file is added, remove the file from that
      scope and save the condition.
