[5.4] [POC] Introduce a @prepend for stack

[themsaid]

@push() will add content to the stack starting from the view being rendered, @prepend will add content to the beginning of the stack.

@stack() will display the $prepends in reverse order + the $pushes in normal order.

// layout.blade

@stack('letters')

// master.blade

@extends('layout')

@push('letters', 'A')

@prepend('letters', 'B')

// welcome.blade

@extends('master')

@push('letters', 'C')

@prepend('letters', 'D')

Having View::make('welcome'), the output will be:

We shouldn't really keep it being called a stack if it supports prepend. Should be renamed to a deque.

[GrahamCampbell]

Probably impractical for us to rename it tho, and impossible in 5.4 anyway.

I need this please. I use stack component in my app for build a breadcrumb system and now i can`t. #17768

I see @append in the example but I don't see where that was added in the compiler?

[themsaid]

@taylorotwell sorry it's push not append

Thanks! I think this should be documented in the Blade doc or the Upgrade Guide.
