RFR(XS): 8214376: Don't use memset to initialize array of Bundle in output.cpp

[Dmitry Chuyko]

Hello,

Please review one liner for one more error reported by GCC 8. Placement 
new is used instead of memset. Generated Bundle constructor does zero 
initialization, so it's similar to memset zeroing.
