Original commit message:
[turbofan] Boost performance of Array.prototype.shift by 4x.
For small arrays, it's way faster to just move the elements instead of
doing the fairly complex and heavy-weight left-trimming. Crankshaft has
had this optimization for small arrays already; this CL more or less
ports this functionality to TurboFan, which yields a 4x speed-up when
using shift on small arrays (with up to 16 elements).
This should recover some of the regressions reported in the Node.js issues
https://github.com/nodejs/node/issues/12657
and discovered for the syncthrough module using
https://github.com/mcollina/syncthrough/blob/master/benchmarks/basic.js
as benchmark.

As of version 13, delegates do not need to worry about colliding tags with the

the format is now suitable for more general use, without opting into the "legacy"

[async-await] (simpler) fix for Return in try/finally in async functions
Alternative approach to https://codereview.chromium.org/2667983004/, which
does not depend on implicit control flow changes from
https://codereview.chromium.org/2664083002
- Remove handling for `async function` from Parser::RewriteReturn(). This functionality
is moved to BytecodeGenerator::BuildAsyncReturn(). This ensures that promise resolution
is deferred until all finally blocks are evaluated fully.
- Add a new deferred command (CMD_ASYNC_RETURN), which instructs ControlScope to
generate return code using BuildAsyncReturn rather than BuildReturn.
- Parser has a new `NewReturnStatement()` helper which determines what type of return
statement to generate based on the type of function.
