Fixed 6873116: Modify reexecute implementation to use pcDesc to record
the reexecute bit
The implementation in this work is mostly from Christian's work on
reexecute/mh bit changes.
Current implementation of reexecute bit uses DebugInfoStreams to record
the reexecute bit by compressing the reexecute bit
into bci field. This makes the code look ugly
(e.g.read_bci_and_reexecute(bool& reexecute). It also makes the future
of debuginfo difficult.
In this work, we use pcDesc to record the reexecute bit obtained from
describe_scope, and then store the reexecute bit to
scopeDesc when a scopeDesc object is created.
