  Log:
    gc.c: reduce parameters for gc_start and garbage_collect
    
    Every time I look at gc.c, I get confused by argument ordering:
    
    gc_start(..., TRUE, TRUE, FALSE, ...)
    gc_start(..., FALSE, FALSE, FALSE, ... )
    
    While we do not have kwargs in C, we can use flags to improve readability:
    
    gc_start(...,
    GPR_FLAG_FULL_MARK | GPR_FLAG_IMMEDIATE_MARK |
    GPR_FLAG_IMMEDIATE_SWEEP | ...)
