    lto: Fix build on MacOS
    
    The build fails on x86_64-apple-darwin19.6.0 starting with 5b6d5a886ee because
    vector is included after system.h and runs into poisoned identifiers.
    
    This patch fixes this by defining INCLUDE_VECTOR before including system.h.
    
    Validated by doing a full build on x86_64-apple-darwin19.6.0.
    
    gcc/lto/ChangeLog:
    
            * lto-partition.cc: Define INCLUDE_VECTOR to avoid running into
            poisoned identifiers.
