05507cc3ea Reland II of 'Optimize trivial regexp disjunctions' CL 1176453002 
This change rewrites regexps like (ab|ac|z|ad|ae|af) into (a[b-f]|z).  We can only reorder disjunctions like this for case-dependent regexps.  For case-independent regexps, the disjunctions should be pre-sorted for best results.

Don't DCHECK when neutering that the buffer is not a SharedArrayBuffer;
instead, just return early.

eb0593e137 [turbofan] Fix context chain extension for top-level code. 
For top-level code the closure passed into context allocation methods
needs to be replaced with a sentinel to canonicalize is to the empty

c14ba5ec48 Drop computed handler count and index from AST. 
These values were computed by the parser and hence out of sync with any
visitor over the AST. Our AST visitor aborts visitation of statement
lists as soon as a jump statement has been reached. Now handler tables
are guaranteed to be dense and fully populated.

3f223ee69b Debugger: PreservePositionScope should clear positions inside the scope. 
The point of this change is so that when emitting code for a call in
FullCodegen::VisitCall, the statement position is not associated to
any code that loads the function, but to the actual CallIC.

cf07add227 Don't create debug context if debug listener is not set 
If there had been no debug listener v8::Debug::GetDebugContext would have created new context and wouln't have kept reference to it. This way we may well end up with several debug contexts and disabled debugger.

As a side effect this change allows to efficiently distinguish debug context from blink contexts by simply comparing handles.
