bab3a57975 Fix RELEASE_ASSERT_NOT_REACHED on CoverInitializedName used as a value 
A CoverInitializedName such as `{ a = 0 }` (object shorthand with default) is
only valid when the enclosing object literal is refined into a destructuring
pattern. When such an object literal is instead consumed as a real value -- the
base of a member access, call, computed access, or tagged template, e.g.
`( {... { a = 0 }. b = 1 } )` -- the pending CoverInitializedName error was
discarded by a later assignment, so no SyntaxError was raised and the
AssignmentPattern property value reached bytecode generation, hitting
RELEASE_ASSERT_NOT_REACHED in Node::generateExpressionByteCode.

Report the pending CoverInitializedName as an early SyntaxError in the two
LeftHandSideExpression member-access loops the moment the base is consumed as a
value, since it can no longer be refined into a pattern.

181019c0c3 Reject object binding pattern rest followed by a binding pattern (Issue #1334) 
BindingRestProperty in an object binding pattern only accepts a
BindingIdentifier, unlike BindingRestElement in an array binding pattern
which also accepts a BindingPattern. Throw a SyntaxError when `...` is
followed by `{` or `[` in a declaration context.

97e8115ab1 Add basics of Chrome Devtools debugger support 
- Use routing table for request dispatch in DebuggerHttpRouter, for
  handling choosing which debugger stack to use based on the http
  upgrade request:
    - DebuggerEscargot for the python debugger and VSCode
    - DebuggerDevtools for connecting to Chrome Devtools
- Parse mesasges with 16bit message size
- Reply to the first few messages chrome sends
- Refactor Debugger:
    - Rename DebuggerRemote to DebuggerEscargot
    - DebuggerEscargot and DebuggerDevtools inherit from
      DebuggerTcp which inherits from Debugger
- Add debugger info to README.md
