    Reason for revert: Broken
    
    Original change's description:
    > [compiler] Don't collect source positions for the top frame
    > 
    > While most source positions were not collected even throwing exceptions,
    > the top frame still was always collected as it was used to initialize
    > the JSMessageObject. This skips even that frame, by storing the
    > SharedFunctionInfo and bytecode offset in the JSMessageObject allowing
    > it to lazily evaluate the actual source position.
    > 
    > Also adds tests to test-api.cc that test each of the source position
    > functions in isolation to ensure that they don't rely on previous
    > invocations to call the source collection function.
    > 
    > Since no source positions are now collected at the point when an
    > exception is thrown, the mjsunit/stack-traces-overflow now passes again
    > with the flag enabled. (cctest/test-cpu-profiler/Inlining2 is now the
    > only failure).
