    Reland "[ic] Fix handling of API properties with side effects" · b4942eb3
    Philip Pfaffe authored
    This is a reland of 0ce36e7d
    
    The reland includes two fixes:
    - Move the EvaluateGlobalForTesting into libv8 to avoid linkage issues
      and to avoid having to export ThreadLocalTop symbols.
    - Give the ExecutionMode enum a uint8_t backing type to avoid endianess
      issues.
    
    Original change's description:
    > [ic] Fix handling of API properties with side effects
    >
    > DebugEvaluate can evaluate expressions in side-effect-free mode, where
    > any operation that would cause observable side effects throws an
    > exception. Currently, when accessors are backed by callbacks, it's
    > possible that ICs call those accessors directly, bypassing the
    > side-effect checks. This CL introduces a bailouts to runtime in those
    > cases.
