ToBoolean was used with conditional jumps. An earlier cl
(https://codereview.chromium.org/1426913002/) merges jumps
and ToBoolean into a single bytecode. So, we no longer need
ToBoolean bytecode.

This operator now provides a second output which indicates whether the conversion from float64 to uint64 was successful or not. The second output returns 0 if the conversion fails, or something else if the conversion succeeds.

The second output can be ignored, which means that the operator can be used the same as the original operator.

I implement the new operator on x64 and arm64. @v8-mips-ports and @v8-ppc-ports, can you please take care of the mips64 and ppc64 implementation of the second output?

The new minorGC pass collects all unmodified objects that are not marked
active by blink. The earlier implementation assumed all new space nodes
to be Heap objects. Updated this code to handle Smi objects as well.

I noticed that using --print-opt-code was producing output unreliably.
Upon investigation, it turns out OFStream's destructor was not marked
virtual. Fixing this fixes the problem, as ostream flushes at destruction.

Instead of iterating the whole map space to find dead transitions,
look in weak cell list and transition array list.

Simple transitions are in the weak cell list.

Full transitions are in the transitions array list.
