de7b222e36 Support for precise stepping in functions compiled before debugging was started (step 2) 
This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.

This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.

Also fixed SortedListBSearch to actually use the passed comparision function.

bfd048173f Notify collector about lazily deoptimized code objects. 
All slots that were recorded on these objects during incremental marking should be ignored as they are no longer valid.

To filter such invalidated slots out during slots buffers iteration we set all markbits under the invalidated code object to 1 after the code space was swept and before slots buffers are processed.

3fabe323f2 Add kHeaderSize constant to SeqString. 
This prevents potential misuse of SeqString::kHeaderSize as in the
case of live byte counting in incremental marking stub. All stubs
picked up the undefined size constant SeqString::kHeaderSize, thus
the computed size of all strings was off by two pointers slots.

610281f4ee Fix calculation of live-bytes in pages. 
The "live bytes" count is *really* a "marked black" count - i.e., the count of bytes *known* to be live.

Fix aggravating bug on X64 where assembler code used a value that was off
by a factor of 2^31.

Ensure that sweeping clears live-bytes. Added other missing increments.

Added print statements to trace live-byte modifications, under a flag.

Still a few cases of undercounting left.
