bad2108d3c LibJS: Add the String.prototype.matchAll method 
This is only the String.prototype side of matchAll, for full
functionality Symbol.matchAll has to be implemented in our RegExp
built-in object.

9f71e3cab4 LibJS: Handle UTF whitespace characters in String's trim{,Start,End} 
This helps a bit, but doesnt handle UTF-16 surrogates in the strings.

9127d83927 LibJS: Rename Value::{is_integer => is_integral_number} 
The implementation matches the specification, so lets match the name
as well. :^)

c619ad4fec LibJS: Allow no-op define property calls on non-configurable objects

ValidateAndApplyPropertyDescriptor.

e1b0719435 LibJS: Add all of the FinalizationRegistry.prototype methods 
More specifically: cleanupSome, register & unregister.

FinalizationRegistery.prototype.cleanupSome is actually still a stage 2
proposal, but since test262 test cases already exist for it, i decided
to go for it :)

1414c7b049 LibJS: Add a basic pass manager and add some basic passes 
This commit adds a bunch of passes, the most interesting of which is a
pass that merges blocks together, and a pass that places blocks that
flow into each other next to each other, and a very simply pass that
removes duplicate basic blocks.
Note that this does not remove the jump at the end of each block in that
pass to avoid scope creep in the passes.

e81fd7106b LibJS: Rename the overridden Instruction methods to foo_impl 
These are pretty hairy if someone forgets to override one, as the
catchall function in Instruction will keep calling itself over and over
again, leading to really hard-to-debug situations.

4c7c7c38e2 LibJS: Make EnterUnwindContext a terminator op 
Otherwise a basic block could have multiple outgoing edges without
having much reason to do so.

Instead of the current incorrect behaviour of just defaulting to an
empty string.

3194177dce LibJS: Correctly parse yield-from expressions 
This commit implements parsing for `yield *expr`, and the multiple
ways something can or can't be parsed like that.
Also makes yield-from a TODO in the bytecode generator.
Behold, the glory of javascript syntax:
```js
// 'yield' = expression in generators.
function* foo() {
    yield
    *bar; // <- Syntax error here, expression can't start with *
}

// 'yield' = identifier anywhere else.
function foo() {
    yield
    *bar; // Perfectly fine, this is just `yield * bar`
}
```

2661a88108 LibJS: Add a test file for generator function parsing 
Note that the yield-from expression tests are skipped for now since
they're not implemented yet.

91fbeeab72 LibJS: Add LoadArgument bytecode instruction for fast argument access 
This is generated for Identifier nodes that represent a function
argument variable. It loads a given argument index from the current
call frame into the accumulator.

848944113c LibJS: Access function arguments directly in AST interpreter 
Instead of doing a generic scoped variable lookup, function arguments
now go directly to the call frame arguments list.

This is a huge speedup on everything that uses arguments. :^)

a733a30373 LibJS: Write computed function default arguments into the call frame 
Previously, default argument values would only show up when accessing
the argument by parameter name. This patch makes us write them back
into the call frame so they can be accessed via VM::argument() as well.

481cef59b6 LibJS: Track which Identifier nodes refer to function arguments 
This patch adds an "argument index" field to Identifier AST nodes.
If the Identifier refers to a function parameter in the currently
open function scope, we stash the index of the parameter here.

This will allow us to implement much faster direct access to function
argument variables.
