Time profiler: optimize json output time Summary: Use llvm::json::Array.reserve() to optimize json output time. Here is motivation: https://reviews.llvm.org/D60609#1468941. In short: for the json array with ~32K entries, pushing back each entry takes ~4% of whole time compared to the method of preliminary memory reservation: (3995-3845)/3995 = 3.75%.
